Whats the fastest way of doing this?

4y-(3y+4/2)+1/3=5(4-y)/3

cheers

Well assuming it's $\frac{3y+4}{2}$ ...

$\frac{5y-4}{2} = \frac{19-5y}{3}$
You know how to get to this, right? (Left hand side common denominator etc.)

$15y-12 = 38-10y$

$25y=50$

$\therefore y = 2$

Or you can plot them both on the calculator (y1, y2) and find the intersection point. That's the fastest way.
