Question

Which would be the first step for solving the equation x + 2 = 18?

A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7

Answer 1

A. Add -2 to both sides

Explanation:

The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

Answer 2

The first step for solving this equation would be adding -2 to both sides of the equation.
