You can put this solution on YOUR website! solve using substitution:
1/5x +1/2y=8
x+y=20
---
Multiply thru the 1st equation by 10 to get rid of the fractions.
2x + 5y = 80
---
Substitute for "y" and solve for "x":
2x + 5(20-x) = 80
---
2x + 100 - 5x = 80
---
-3x = -20
x = 20/3
-----
Solve for "y";
x+y = 20
(20/3) + y = (60/3)
y = 40/3
