John and Maria solved the same equation using two different methods. Compare and contrast John and Maria’s methods. Explain how they arrived at the same solution.

John's steps

-distrubute the 2 through the parentheseas

-subtract 18-12

-subtract 10 on both sides

-divide both sides of the equation by 2

-y=-2

Marias steps

-divide both sides by 2

-subtract both sides by -5

-y=-2
