Question

solve the system of equations below.
2x + 2y = 12
3x + 2y = 17

Answer 1

do the same thing you just did with pooja but subtract 2-3=? 2-2=? 12-17=?

Answer 2

i got 1x + 0y = 5
but what do i do next?

Answer 3

it actually -x=-5 but that equals x=5...
anyways. now you substitute x in one of the equations (lets use the first one)
so 2(5)+2y=12

Answer 4

10+2y=12
-10 -10
2y=2
y=1
and x=5
