Question

4x-18y=9
Now I know you have to get y alone so I add x to the other side. Would it be -18y= 4x+9? I know how to get to the answer, you divide the right side by 18...I'm just making sure it is written down correctly.

Answer 1

4x-18y=9
-18y=9-4x (subtract both side by 4x)
y=-(9-4x)/18 (divide both side by -18)

Answer 2

I thought it was:
4x-18y=9
4(0) - 18y = 9
18y = 9
/18 /18
y = .5 but now i see it makes no sense...

Answer 3

So then would that make it y=-2/9 + 1/2?

Answer 4

oops I meant y=-2/9x+1/2

Answer 5

2/9x-1/2

Answer 6

Oh,, okay. Thanks!

Answer 7

no problem :)
