Answer:
2x - (3 + 4x) = 12
x = -7.5
y = -27
Step-by-step explanation:
-4x + y = 3 (1)
2x - y = 12 (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
2x - 3 - 4x = 12
2x - 4x = 12 + 3
-2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (2)
2x - y = 12 (2)
2(-7.5) - y = 12
-15 - y = 12
-y = 12 + 15
- y = 27
y = -27
Answer:
