Question

Use the substitution method to solve the system of equations. Choose the correct ordered pair. 3x – y = 7 2x – 2y = 2

Answer 1

Y=2, and x=3 so it is c

Answer 2

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)
