Steps for finding the solution

We have 3x + 12 = -6

First, we move the non x terms to the RHS of the equation. To do this, we subtract 12 from both sides.

Note: if a = b, then a - c = b - c

Therefore, 3x + 12 - 12 = -6 - 12

or, 3x = -18

Next, divide both sides by 3, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

3x/3 = -18/3

x = -18/3

To simplify, divide both numerator and denominator by 3, which is the GCF of 18 and 3:

x = -6/1 or, x = -6
