Question 245599: y = x + 5
4x + y = 20
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! y = x + 5
4x + y = 20
------------------
Substitute for "y" in the 2nd equation; then solve for "x":
4x + (x+5) = 20
5x = 15
x = 3
-----------------------
Since y = x+5, y = 3+5, y = 8
---------------------------------
Solution: (3,8)
