Answer
(4,7)
Work Step by Step
You have the equations:2x+2y=22 and y=2x-1. Solve:
2x+2(2x-1)=22 -plug in the second equation into the first and distribute-
2x+4x-2=22 -combine like terms-
6x-2=22 -add 2 to both sides-
6x=24 -divide both sides by 6-
x=4
Plug in x=4 into one of the equations:
2(4)+2y=22
8+2y=22
2y=14
y=7
The solution is (4,7)
