Answer:

The solution set is (3,2)

C is correct

Step-by-step explanation:

Given: System of equation.

3x-y=7

2x-2y=2

We will solve x and y using substitution method.

3x-y=7

y=3x-7------------------(1)

Substitute into 2x-2y=2

2x-2(3x-7)=2

2x-6x+14=2

-4x=-12

x=3

Put x=3 into eq(1)

y=3(3)-7

y=2

Hence, The solution set is (3,2)
