solve for y:

6x-2y=18

I got Y=18-6x-2

not sure if thats right or if it's a +2?

Thank you in advance

$\displaystyle 6x-2y=18$

$\displaystyle -2y=18-6x$

$\displaystyle y=\frac{18-6x}{-2}$

$\displaystyle y=-9+3x$

$\displaystyle y=3x-9$

It should be a negative 2 you divide by...if you divided by positive 2, then you would be left with $\displaystyle -y=\frac{18-6x}{2}$ then you would just end up dividing through by negative one.

Then you can simplify further and divide 18 and 6 by negative two to get rid of the fraction.

Looks good! :) - Apr 28th 2008, 09:26 PMshannond
