Answer:

I will assume you are trying to find x and y. x = -1, y = 0=9

Step-by-step explanation:

Multiply the second equation by 7 and subtract the two.

14x + 5y = 31

-(14x - 21y = -203)

This gives 26y = 234. Divide both sides by 26. y = 9

Then substitute y into any equation. I'll use 2x - 3y = -29

2x -3(9) = -29

2x - 27 = -29

2x = -2

x = -1

Y=1/3x-3<br> Y=-x+5 <br> How do I solve
ehidna [41]

Since both equations are equal to y, we can just combine them like this:

1/3x-3=-x+5

1/3x=-x+8

4/3x=8 (since x is 1x which is 3/3x)

x=6

Plug x back in:

y=-6+5

y=-1

So x=6 and y=-1

Hope this helped!
