Set each equation equal to either x or y.
I’ll do x.
x+2y-2y = 3-2y
(Simplify) x = 3-2y
x-y+y = 6+y
(Simplify) x = 6+y
(Set them equal to each other)
3-2y = 6+y
3-2y-6 = 6+y+2y
-3 = 3y
y = -1
x =5
Answer:
x=5
y=-1
Step-by-step explanation:
x+2y=3
x-y=6
x+2y=3
x=6+y
(6+y)+2y=3
x=6+y
6+y+2y=3
x=6+y
6+3y=3
x=6+y
3y=3-6
x=6+y
3y=-3
x=6+y
y=-3/3
x=6+y
y=-1
x=6-1
y=-1
x=5
