Answer:

x = -2, y = -7

Step-by-step explanation:

x - y = 5 ... (1)

-3x + y = -1 ... (2)

Make y the subject from equation (1)

y = x - 5 ... (3)

Substitute equation (3) in (2)

-3x + x - 5 = -1

-2x - 5 = -1

-2x = -1 + 5

-2x = 4 Divide both sides by -2

x = 4 / -2

x = -2

Substitute the value x = -2 i. equation (3)

y = -2 -5

y = -7

Therefore,

x, y = -2, -7
