Answer:
2y=8-x
y-2x=-1
y-2x=-1
y = 2x-1
Substitute for y in the 1st
2(2x-1)=8-x
4x-2=8-x
5x = 10
x = 2
y=2x-1
y = 3
Explanation:
2y=8-x
y-2x=-1
------------
Rearrange:
x = 8-2y
y = 2x-1
------------
Substitute to get:
y = 2(8-2y)-1
y = 16-4y-1
5y = 15
y = 3
-------------------
Substitute to solve for "x":
x = 8-2(3)
x = 2
