Answer:

x=11, y=13

Step-by-step explanation:

3x-2y=7

3x-2(x+2)=7 .          - x + = -      -2*+2=-4

3x-2x-4=7

1x-4=7

x=7+4

x=11

y=x+2

y=11+2

y=13
Answer:
(11, 13)
Explanation:
The first step when you multiply -2 times 2 would equal -4
Then you would
3x-2x-4=7
x-4=7
x=11
y=x+2
y=11+2
y=13
The error Carolyn made was not multiplying the negative and positive number right.
