Answer:

see below

Explanation:

Carolyn made in error on the left side of her work page, in step 2.

When she was distributing the -2 among the numbers in parenthesis, she added 4, instead of subtracting 4.

Her work should look like this:

$3x-2y=7\\3x-2(x+2)=7\\3x-2x-4=7\\x-4=7\\x=11$
$y=x+2\\y=11+2\\y=13$

(11,13)

Hope this helps! :)
