Solve for x: 2x - 4x - 3 = -27

Answer 1

To solve for x, we need to combine like terms and isolate x.

2x - 4x - 3 = -27

Combine like terms:

-2x - 3 = -27

Add 3 to both sides of the equation:

-2x = -27 + 3
-2x = -24

Divide both sides by -2:

x = -24 / -2
x = 12

Therefore, the solution is x = 12.

Answer 2

Solve for x: - 4(3x + 10) - 2 = 54

Answer 3

To solve for x, we need to simplify the equation by applying the distributive property and combining like terms.

-4(3x + 10) - 2 = 54

Start by distributing the -4:

-12x - 40 - 2 = 54

Combine like terms:

-12x - 42 = 54

To isolate x, we need to get rid of the constant term on the left side of the equation by adding 42 to both sides:

-12x - 42 + 42 = 54 + 42
-12x = 96

Next, divide both sides by -12 to solve for x:

x = 96 / -12
x = -8

Therefore, the solution is x = -8.

Answer 4

Solve for x: 20x - 5(6x + 15) = -45

Answer 5

To solve for x, we need to simplify the equation by applying the distributive property and combining like terms.

20x - 5(6x + 15) = -45

Start by distributing the -5:

20x - 5*6x - 5*15 = -45

Simplify:

20x - 30x - 75 = -45

Combine like terms:

-10x - 75 = -45

To isolate x, we need to get rid of the constant term on the left side of the equation by adding 75 to both sides:

-10x - 75 + 75 = -45 + 75
-10x = 30

Next, divide both sides by -10 to solve for x:

x = 30 / -10
x = -3

Therefore, the solution is x = -3.
