Question

Solve by elimination
9x - 3y = 24

7x - 3y = 20

I got (6,-1) is that correct

Answer 1

Nopsie.

Answer 2

No soorry that isnt't correct, do you want to know the correct answer and how to do it?

Answer 3

Start by multiplying the bottomequation by -1 and see what you can get from there :P

Answer 4

First multiply the second equation by -1 and add it to the first equation. By doing this the y value will be eliminated

Answer 5

So:
9x-3y=24
-7x+3y=-20
=
2x+0=4
x=2

Answer 6

lol thx

Answer 7

Now to solve for y you first substitute the x value into either equation
9(2)-3y=24
18-3y=24
-3y=6
y=-2
