ANSWER

x = 2; y = -3

Step-by-step explanation

We have two equations given:

y = -5x + 7

y = -2x + 1

We can equate both equations because they both yield y.

That is:

-5x + 7 = -2x + 1

Collect like terms:

7 - 1 = -2x + 5x

=> 3x = 6

Divide through by 3:

x = 6/3

x = 2

From the first equation:

y = -5(2) + 7

y = -10 + 7

y = -3

Therefore, the solution to the system of equations is x = 2 and y = -3
