Solve the system using elimination. x − 4y = 4 and -3x − 4y = 12
1 answer:
x - 4y = 4
-3x - 4y = 12
Subtract the first equation from the second
x - 4y = 4
-4x = 12
Divide the second equation by (-4)
x - 4y = 4
x = -3
Subtract the second equation from the first
- 4y = 7
x = -3
Divide the first equation by (-4)
y = -7/4
x = -3
<h3>
So, the solution is x = -3 and y = - 7/4</h3>
