Systems of equations:
3x-5y=8
2x+5y=22

3x-5y=8     2x+5y=22

Solve second equation for x; first subtract 5y from each side.

2x=-5y+22    (Divide by 2)

x=-5/2y+11   (Substitute into x into the first equation)

3 (-5/2y+11)-5y=8  (Simplify )

-15/2y +33-5y=8   (Combine like terms)

-25/2y+ 33=8   -25/2y=-25  (Divide each side by -25)

1/2y=1    y=2    Therefore 3x-5(2)=8   3x-10=8   3x=18   x=6

x=6, y=2

- Hope this helps!

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
