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
