Answer:
X = 7 and 3
Step-by-step explanation:
You need to have y by itself.
Doing this you get:
-4y = -1x - 7
2y = 1x + 3
The next step is that we need to simplify y to be just 1y.
y= 1/4x +7/4
y= 1/2x +3/2
Then for solving for X.
X = 7 -> the 4‘s in the denominator cancel one another
X = 3 -> the 2’s in the denominator cancel one another
