Isolating Variables - urgent (due tomorrow)
I am not the best math student and I need help in knowing what to do in this equation.

y 2x
_ + _ = 11
3 5

Sorry if that wasn't in the best format.

I need to figure out how to isolate the y variable.

Help?

I'm imagining you mean (y/3) + (2x/5) = 11
in this case
multiply everything by 3
then move all the terms except Y to the other side (by subtracting them from both sides)
then Y is on it's own

Is the question to isolate y in the equation $\displaystyle \frac{y}{3} + \frac{2x}{5} = 11$?

If so, first subtract 2x/5 from both sides:

$\displaystyle \frac{y}{3} = 11 - \frac{2x}{5}$

Then multiply both sides of the equation by 3:

$\displaystyle y = 33 - \frac{6x}{5}$

I did iceman's method and got the correct answer but once again thank you both!

It was a great deal of help! :D
