Question 887620: Did help understanding solving equation by process of elimination
Problem. 12x+10y=86 and x+y=8. Very confused.

You can put this solution on YOUR website!
1.12x%2B10y=86
2.x%2By=8
Multiply eq. 2 by -12 and add to eq. 1 to eliminate x,
12x%2B10y-12x-12y=86-96
-2y=-10
highlight%28y=5%29
Now use either equation to solve for x.
x%2B5=8
highlight%28x=3%29
