Solve by the addition method
4x+3y=15 and 2x-5y=1

You can put this solution on YOUR website!
4x%2B3y=15....eq.1
2x-5y=1.....eq.2. ..both sides multiply by -2
__________________________
4x%2B3y=15....eq.1
-4x%2B10y=-2.....eq.2
_____________________________add both eq.1 and eq.2
4x%2B3y%2B%28-4x%2B10y%29=15%2B%28-2%29
cross%284x%29%2B3y-cross%284x%29%2B10y=15-2
3y%2B10y=13
13y=13
y=13%2F13
highlight%28y=1%29
go to eq.2, substitute 1 for y

2x-5%2A1=1.....eq.2
2x-5=1
2x=1%2B5
2x=6
x=6%2F2
highlight%28x=3%29
solution- or intersection point is (3,1)
