2X+3Y=1 MULTIPLY THIS EQUATION BY 3 & WE GET 6X+9Y=3
-3X+4Y=-10 MULTIPLY THIS EQUATION BY 2 WE GET -6X+8Y=-20
NO ADD THESE TWO EQUATIONS
6X+9Y=3
-6X+8Y=-20
-----------------------------------
17Y=-17
Y=-17/17
Y=-1 SOLUTION
2X+3*-1=1
2X-3=1
2X=1+3
2X=4
X=4/2
X=2 SOLUTION
PROOF
-3*2+4*-1=-10
-6-4=-10
-10=-10
