What is the value of y?
mrs_skeptik [129]
Ok so you would start by getting rid of the fraction. You should know the steps for that by now but here this is what it would look like
3y/4+10=2y/4 Simplify
3y/4+10=1y/2
10=-1y 
I really simplified the last part but this is what it looks like:  \frac{2y}{4}- \frac{3y}{4} = -1y
10=-1y
y=-10
