Use the information to answer the following question.

Carolyn was asked to solve the following system of equations.



Her work is shown.

Step 1: 3x – 2y = 7

Step 2: 3x – 2(x + 2) = 7

Step 3: 3x – 2x + 4 = 7

Step 4: x + 4 = 7

Step 5: x = 3

Step 6: y = x + 2

Step 7: y = 3 + 2

Step 8: y = 5

Solution: (3, 5)
