\begin{aligned} 6x+2y &= -2 3x-2y &= -5 \end{aligned}
6x+2y
3x−2y


=−2
=−5

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

the correct answer is d
