Question

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

Answer 1

Subtract the second equation from the first equation. That will eliminate the y

Answer 2

That doesn't help me much

Answer 3

you can solve for y in the first equation so get y = 1- 2x.
then you can plug this into the second equation to replace y
so then you can solve it like -3x+(1-2x)=-9 and solve from there xD
then plug the answer you get for x back into 1 - 2x to get y value

Answer 4

No I know how to subtract but what do I do with what I get after subtracting?

Answer 5

subtract equation 2 from equation 1

2x+y=1
-3x+y=-9
----------
5x + 0y = 10

5x = 10

Answer 6

solve 5x = 10 for x

then use this to find y
