.
5x+4y=6 Multiply this by 2. This will help get 2 equations with equal x's.
10x+8y=12 Add this below.
.
-2x-3y=-1 Multiply this by 5.
-10x-15y=-5 Add equation from above.
(-10x-15y)+(10x+8y)=-5+12
-7y=7
y=-1 Substitute this in one of the original equations.
5x+4y=6
5x+4(-1)=6
5x-4=6
5x=10
x=2
.
CHECK (Use the other original equation):
-2x-3y=-1
-2(2)-3(-1)=-1
-4+3=-1
-1=-1
.
The answer is (2,-1)
