Answer:

(-1,5)

Step-by-step explanation:

Solve the following system:

2 y + x = 9 | (equation 1)

2 y + 3 x = 7 | (equation 2)  

Subtract equation 2 from equation 1:

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

- 2 x = 2

x = - 1

Substitute into question 1:

2 y - 1 = 9

y = 5

Answer: x = -1 , y = 5
