Answer:
x=2, y=3
Explanation:
y+x=5, subtract x from both sides you get, y=-x+5
since y also equals x+1, you can tell x+1=-x+5,
add x to both sides you get, 2x+1=5
subtract 1 from both sides you get, 2x=4
divide both sides by 2 and you get, x=2.
Now sub in 2 for x in any of the equations to get y.
y=x+1. y=(2)+1, y=3.
