Answer:
(4, -7)
Step-by-step explanation:
3x + y = 5
x - 4y = 32
Solve the 2nd equation for x
x = 4y + 32
Plug this in for variable x into equation 1
3 · (4y + 32) + y = 5
Solve for y
3 · (4y + 32) + y = 5
12y + 96 + y = 5
13y + 96 = 5
13y = -91
y = -7
Plug this in for variable y into equation 2
x - 4(-7) = 32
x - (-28) = 32
x + 28 = 32
x = 4
Conclusion:
y = -7
x = 4
