You can put this solution on YOUR website! 3X+1=-7Y
3X+7Y=-1
-(6X+7Y=0) NOW SUBTRACT THESE 2 EQUATIONS.
----------------------------
-3X=-1
X=-1/-3
X=1/3 SOLUTION. SUBSTITUTING 1/3 FOR X IN EITHER EQUATION WE SOLVE FOR Y
3*1/3+1=-7Y
1+1=-7Y
7Y=-2
Y=-2/7 SOLUTION
PROOF
6*1/3+7(-2/7)=0
2-14/7=0
2-2=0
0=0
