(-4,-13)

Answer 2

@LilStacie

Giving the answer like that is
a) Not permitted in the code of conduct
b) not helpful to the poster - she has no way of knowing that oyu are correct and learns NOTHING from copying your answer

@siahniya16 you jave 2 equations both telling you y=?

the solution is when both those equations are true

so you can write y = 3x+7 = x-9

or
3x+7 = x-9

can you work out what x is from that?

Answer 3

@lilstacie
you answer is not correct either!

Answer 4

you have 2 equations both telling you y=?

the solution is when both those equations are true

so you can write:
y = 3x+7 = x-9

or
3x+7 = x-9

can you work out what x is from that?

Answer 5

just do : 3x + 7 = x - 9 and solve for x. Once x is found, sub that back into either of the original equations to find y
