-X+3Y=-1
-X=-3Y-1 OR X=3Y+1 NOW SUBSTITUTE (3Y+1) FOR X IN THE OTHER EQUATION
4(3Y+1)-12Y=5
12Y+4-12Y=5
4=5 THIS WOULD INDICATE THAT THERE IS NO SOLUTION TO THIS SET OF EQUATIONS.
TRY ADDING THESE 2 EQUATIONS YOU GET THE SAME RESULT
4X-12Y=5 NOW MULTIPLY THE SECOND EQUATION BY 4 & ADD
-4X+12Y=-4
---------------------------------
0X+OY=1
0=1 AGAIN NO SOLUTION.
