Question 22489: I need to rewrite the equation so that y is a fuction of x:
-2x+5y-6=-11
6+-2x+5y-6=-11+6
1/2x*-2x+5y=-5*1/2x
This is as far as I got, please help.
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
Your first step is correct:
-2x+5y-6=-11
6+-2x+5y-6=-11+6
-2x + 5y = -5

However, the next step is incorrect. You need to "UNDO" the -2x by adding +2x to both sides of the equation. It should look like this:
2x -2x +5y = 2x - 5
5y = 2x -5

Next, you must "UNDO" the 5 that was multiplied by the y. In order to "UNDO" multiplication, you must DIVIDE both sides by 5. There are two ways to write this:

OR YOU CAN WRITE:

Both answers are correct.
