You can put this solution on YOUR website!
multiply the top by 10
8x-35y=5 and the bottom by 5
3x-20y=-5
multiply the top by 4 and the bottom by -7
32x-140y=20
-21x+140y=35
11x=55
x=5
4-3.5y=0.5
-3.5y=-3.5
y=1
(5, 1)
Trying to remove fractions is often helpful. Check, however, in the original equations.
