13x - 6y = 20
7x + 4y = 18

2

1

-2

-1

Answer 1

set one of the equations to be x= and then plug it into the other equation

Answer 2

in this equation u say screw the Y's!
13x-6=20

so x is = 2 then u look at the second problem so u know x=2
7x+4y=18
7*2=14 so its 14+4y=18
y = 1
so your answers are
x =2
y=1
