Answer:
Solve for x.
Step 1: Add y to both sides.
2x−y+y=120+y
2x=y+120
Step 2: Divide both sides by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{y+120}{2}[/tex]
x = [tex]\frac{1}{2}[/tex]y + 60
solve for y.
Step 1: Add -2x to both sides.
2x−y+−2x=120+−2x
−y=−2x+120
Step 2: Divide both sides by -1
[tex]\frac{-y}{-1}[/tex] = [tex]\frac{-2x + 120}{-1}[/tex]
y=2x−120
