You can put this solution on YOUR website!
1.y=x%2B8+
2.+x%2By=2
Use substitution, substitute eq. 1 into eq. 2 and solve for x.
x%2B%28x%2B8%29=2
2x%2B8=2
2x=-6
highlight%28x=-3%29
Now use eq. 1 to solve for y.
y=-3%2B8
highlight%28y=5%29

Verify by plugging the solutions into the original equations.
y=x%2B8
5=-3%2B8
5=5
True.
x%2By=2
-3%2B5=2
2=2
True.
It's a good solution.
