Chose the substitution method to solve the system of equations choose the correct ordered pair 3x-y=7 2x-2y2

(3, 2)

Step-by-step explanation:

3x-y=7

2x-2y=2

y=3x-7

substitute this equation to 2x-2y=2

first, simplify 2x-2y=2 into x-y=1.

x-(3x-7)=1

x-3x+7=1

-2x+7=1

-2x=1-7

-2x=-6

x=-6/-2=3

y=3(3)-7=9-7=2

x=3, y=2.
