Answer:
x=4-y
x=4−y
Step-by-step explanation:
1 Factor out the common term 22.
-2(x+y)=-8
−2(x+y)=−8
2 Divide both sides by -2−2.
x+y=\frac{-8}{-2}
x+y=
−2
−8
3 Two negatives make a positive.
x+y=\frac{8}{2}
x+y=
2
8
4 Simplify \frac{8}{2}
2
8
to 44.
x+y=4
x+y=4
5 Subtract yy from both sides.
x=4-y
x=4−y
Done
