Solve: -3x + 12 = -18

x=10

Step-by-step explanation:

We are given the equation:

and asked to solve for x. Therefore, we must isolate x on one side of the equation.

12 is being added to -3x. The inverse of addition is subtraction. Subtract 12 from both sides of the equation.

x is being multiplied by -3. The inverse of multiplication is division. Divide both sides of the equation by -3.

Let's check our solution. Plug 10 in for x and solve.

Multiply -3 and 10.

Add 12 to -30.

This checks out, so we know our solution is correct.

The solution -3x+12=-18 is x=10.
