Question

Solve: 1/3(g) - 12 = -15

Answer 1

$\frac{1}{3} g - 12 = - 15 \\ \frac{1}{3} g = - 3 \\ g = - 9$

Answer 2

How should you start this problem?

You want to solve this problem by keeping all the terms with the variable you want to solve for on one side of the equation, and the rest of the terms on the other side of the equation.

We will keep terms with the variable g on the left side of the equation and move everything else to the right side of the equation.

Solving for g.

1. Start by adding 12 to both sides of the equation to isolate the term containing the variable g.

1/3g = -3

2. Solve for the variable g by dividing both sides by 1/3. You could also multiply both sides by 3. After doing this step you will get your final answer.

g = -9
