4x^2+3y=y+1/3 I'm stuck thanks

**Anonymous**, Monday, February 18, 2013 at 9:35pmIf all you need to do is solve for x and y then this is what I would do:

first solving for y

4x^2+3y=y+(1/3) multiply everything by 3 to get rid of (1/3)

12x^2+9y=3y then isolate y

(12x^2)/(-6)=y

then solving for x

go back a few steps to get 12x^2=-6y (this is just rearranging the y= equation)

solve that for x and you should get x=sqrt(-y/2)

i hope this helps- it seems to simple for college algebra, but there you go.

**Reiny**, Monday, February 18, 2013 at 10:13pmthe 4th line should have been

12x^2+9y=3y + 1

you probably wanted to solve for y, thus expressing it as a function:

6y = -12x^2 + 1

y = -2x^2 + 1/6
