Answer:

No, no it is not.

Step-by-step explanation:

First step : Solve for y in − 2 x + y = − 7.

y = 2 x − 7

Second step : Substitute y = 2 x - 7 into 3 x + 2 y = 10.

7 x − 14 = 10

Solve for x in 7 x - 14 = 10.

x = 24 / 7

Substitute x = 24 / 7 into y = 2 x - 7.

- 1 / 7

That means your answer is.

x = 24 / 7

y = − 1 / 7
