4(y + 2) = 5(y - 5)

21 answers

To solve this equation, let's start by distributing the 4 on the left side and the 5 on the right side:

4(y + 2) = 5(y - 5)
4y + 8 = 5y - 25

Next, let's isolate the variable terms by subtracting 4y from both sides of the equation:

8 = y - 25

Now, let's isolate the constant terms by adding 25 to both sides of the equation:

8 + 25 = y
33 = y

The solution to the equation is y = 33.
2x + 6 - 3x - 4 = 9x - 10x - 1
Let's simplify and solve the equation step by step:

2x + 6 - 3x - 4 = 9x - 10x - 1

First, combine like terms on each side of the equation:

(-x) + 2 = -x - 1

Next, subtract -x from both sides to simplify the equation further:

(-x) + 2 + x = -x - 1 + x

2 = -1

However, since the equation is not true (2 does not equal -1), there is no solution to this equation.
x/5 = -15 8
To solve for x in the equation x/5 = -15 8, we'll first simplify and isolate x.

Adding the negative value 15 8 to both sides of the equation, we have:

x/5 + 15 8 = 0

Next, we need to convert 15 8 into a fraction. 15 is the whole number and 8 is the fractional part. So, 15 8 can also be written as 15 + 8.

Thus, the equation becomes:

x/5 + 151 8 = 0

To add the fractions, we'll first find a common denominator, which is 8 for 5 and 151 8.

Converting 5 to an equivalent fraction with a denominator of 8, we get 40/8.

Therefore, the equation becomes:

x/40 + 151 8 = 0

To combine the fractions, we add the numerators and put them over the common denominator:

(x + 151)/40 = 0

Now, to solve for x, we'll multiply both sides of the equation by 40:

40(x + 151)/40 = 0 * 40
x + 151 = 0

Finally, to isolate x, we'll subtract 151 from both sides of the equation:

x + 151 - 151 = 0 - 151
x = -151

The solution to the equation is x = -151.
x/5 = -15 - 8
To solve for x in the equation x/5 = -15 - 8, we'll first simplify and isolate x.

Subtracting -15 and -8 on the right side of the equation:

x/5 = -15 - 8

Simplifying:

x/5 = -23

Next, to eliminate the fraction, we'll multiply both sides of the equation by 5:

5 * (x/5) = -23 * 5

Simplifying:

x = -115

The solution to the equation is x = -115.
x/5 = -15 + 8
To solve for x in the equation x/5 = -15 + 8, we'll first simplify and isolate x.

Adding -15 and 8 on the right side of the equation:

x/5 = -7

Next, to eliminate the fraction, we'll multiply both sides of the equation by 5:

5 * (x/5) = -7 * 5

Simplifying:

x = -35

The solution to the equation is x = -35.
2(6x - 2) = 10x
Let's solve the equation step by step:

2(6x - 2) = 10x

First, we'll distribute the 2 on the left side:

12x - 4 = 10x

Next, let's simplify and isolate the variable terms by subtracting 10x from both sides:

12x - 10x - 4 = 10x - 10x

2x - 4 = 0

Now, let's isolate the constant terms by adding 4 to both sides:

2x - 4 + 4 = 0 + 4

2x = 4

To find the value of x, we'll divide both sides by 2:

2x/2 = 4/2

x = 2

The solution to the equation is x = 2.
x/6 - 5 = -12
To solve the equation x/6 - 5 = -12, we'll first simplify and isolate x.

Adding 5 to both sides of the equation:

x/6 - 5 + 5 = -12 + 5

x/6 = -7

Next, to eliminate the fraction, we'll multiply both sides of the equation by 6:

6 * (x/6) = -7 * 6

Canceling out the 6 on the left side:

x = -42

The solution to the equation is x = -42.
6(x + 2) - (6x + 12) = 0
To solve this equation, let's start by simplifying each side of the equation:

6(x + 2) - (6x + 12) = 0

Distributing the 6 on the left side:

6x + 12 - (6x + 12) = 0

Next, simplify the expressions within the parentheses:

6x + 12 - 6x - 12 = 0

Combining like terms:

(6x - 6x) + (12 - 12) = 0

Both terms simplify to zero:

0 + 0 = 0

Therefore, the equation is true for any value of x. This means that the solution is any real number.
5(x + 3) = (5x + 15)
To solve this equation, let's distribute the 5 on the left side:

5(x + 3) = (5x + 15)

This gives us:

5x + 15 = 5x + 15

Now, let's simplify and isolate the variable terms by subtracting 5x from both sides:

5x - 5x + 15 = 5x - 5x + 15

This simplifies to:

15 = 15

Since 15 is equal to 15, this equation is true for any value of x. Therefore, the solution is any real number.
x + 2 = -28 + 6
To solve this equation, let's simplify and isolate x.

Start by simplifying -28 + 6 on the right side:

x + 2 = -22

Next, to isolate x, subtract 2 from both sides of the equation:

x + 2 - 2 = -22 - 2

This simplifies to:

x = -24

Therefore, the solution to the equation is x = -24.
2(6x - 8) = 13x
Let's solve the equation step by step:

2(6x - 8) = 13x

First, distribute the 2 on the left side of the equation:

12x - 16 = 13x

Next, simplify and isolate the variable terms by subtracting 13x from both sides of the equation:

12x - 13x - 16 = 13x - 13x

-x - 16 = 0

Now, isolate the constant term by adding 16 to both sides of the equation:

-x - 16 + 16 = 0 + 16

-x = 16

Finally, multiply both sides of the equation by -1 to solve for x:

(-1)(-x) = (-1)(16)

x = -16

The solution to the equation is x = -16.
