One way to solve is to try to cancel out some terms we till try to cancel out the y terms
-4x+5y=14 7x+3y=-1 find lcm of 3 and 5 the lcm=15 -4x+5y=14 multily by 3 -12x+15y=42
7x+3y=-1 multiply both sides by -5 -35x-15y=5 add 2 equations together -12x-35x+15x-15x=42+5 add like terms -47x=47 divide both sides by 47 -x=1 multpiply by -1 x=-1
subsitute -1 for x in one quation
7x+3y=-1 x=-1 7(-1)+3y=-1 -7+3y=-1 add 7 to both sides 3y=6 divide both sides by 3 y=2
