To solve the equation 2x + 4 = 8, we need to isolate the variable x.
Subtract 4 from both sides of the equation:
2x + 4 - 4 = 8 - 4
2x = 4
Next, divide both sides of the equation by 2:
2x/2 = 4/2
x = 2
So, the solution to the equation 2x + 4 = 8 is x = 2.
2x + 4 = 8

How old am I if 600 reduced by 3 times my age is 542?
Let's say your age is represented by the variable "x".
The given information states that "600 reduced by 3 times your age is 542". We can express this as an equation:
600 - 3x = 542
Now, let's solve this equation for x.
First, subtract 600 from both sides of the equation:
600 - 3x - 600 = 542 - 600
-3x = -58
Next, divide both sides of the equation by -3:
-3x / -3 = -58 / -3
x = 19.33
Hence, if 600 reduced by 3 times your age is 542, your age is approximately 19.33 years.

Apologies for the mistake in the previous response. Let's solve the equation correctly:
We are given that "600 reduced by 3 times your age is 542". So, we can write this as an equation:
600 - 3x = 542
Now, let's solve this equation for x:
First, subtract 600 from both sides of the equation:
600 - 3x - 600 = 542 - 600
-3x = -58
Next, divide both sides of the equation by -3:
-3x / -3 = -58 / -3
x = 58 / 3
x ≈ 19.33
Apologies for the earlier incorrect statement. If 600 reduced by 3 times your age is 542, your age is approximately 19.33 years old.

14 = 3 + 2x
To solve the equation 14 = 3 + 2x, we need to isolate the variable x.
Subtract 3 from both sides of the equation:
14 - 3 = 3 + 2x - 3
11 = 2x
Next, divide both sides of the equation by 2:
11/2 = 2x/2
x = 11/2
x = 5.5
So, the solution to the equation 14 = 3 + 2x is x = 5.5.
Subtract 3 from both sides of the equation:
14 - 3 = 3 + 2x - 3
11 = 2x
Next, divide both sides of the equation by 2:
11/2 = 2x/2
x = 11/2
x = 5.5
So, the solution to the equation 14 = 3 + 2x is x = 5.5.
-5(k - 2) = 40
To solve the equation -5(k - 2) = 40, we need to isolate the variable k.
First, let's distribute the -5 to the terms inside the parentheses:
-5k + 10 = 40
Next, let's isolate -5k by subtracting 10 from both sides of the equation:
-5k = 40 - 10
-5k = 30
To solve for k, divide both sides of the equation by -5:
-5k / -5 = 30 / -5
k = -6
Therefore, the solution to the equation -5(k - 2) = 40 is k = -6.
First, let's distribute the -5 to the terms inside the parentheses:
-5k + 10 = 40
Next, let's isolate -5k by subtracting 10 from both sides of the equation:
-5k = 40 - 10
-5k = 30
To solve for k, divide both sides of the equation by -5:
-5k / -5 = 30 / -5
k = -6
Therefore, the solution to the equation -5(k - 2) = 40 is k = -6.
