2x + 12 = 18 – x

To solve the equation 2x + 12 = 18 - x, you need to isolate the variable x on one side of the equation.

Step 1: Combine like terms

2x + x + 12 = 18 - x + x

3x + 12 = 18

Step 2: Move the constant to the other side of the equation

3x = 18 - 12

3x = 6

Step 3: Divide both sides by 3 to solve for x

3x/3 = 6/3

x = 2

Therefore, the solution to the equation 2x + 12 = 18 - x is x = 2.
