5x+4y=22.......eq 1
3x+4y=10.......eq 2
:
subtract equation 1 from equation 2
:
y terms are eliminated because 4y-4y=0. We are left with 5x-3x=22-10
:
2x=12
:
highlight%28x=6%29
:
take the found value of x and plug it back into either equation
:
3(6)+4y=10--->18+4y=10--->4y=-8
:
highlight%28y=-2%29
