What is

x=3y-1

x=-2y+9

Since both equal x, just subsitute them

3y-1=x=-2y+9

3y-1=-2y+9

add 2y to both sides

5y-1=9

add 1 to both sides

5y=10

divide both sides by 5

y=2

sub back into any equation

x=3y-1

x=3 (2) - 1

x=6-1

x=5

x=5

y=2

(5,2)

Are you to combine the answer or are they 2 separate equations you need to solve for y?
