Solve for y
x2y/5=3(y+2)/4 +3
This is what I did and I don't know if it's right or what to do next. Find the Lcd which is 20.
I get: 4x8y=15y+30=60 I don't know what to do from here. I'm so confused.

From your work, it appears that the original expression is:
(x2y)/5=3(y+2)/4 +3
If that is the case, your intermediate calculation is correct:
4x8y=15y+30+60
From here, you will group all terms containing y to the left hand side, and everything else to the right to get:
15y8y=4x+30+60, or
23y = 4x + 90
Now divide by the coefficient of y, namely 23:
y = (4/23)x  90/23
Substitute this value of y into the left and right hand sides of the original equation to make sure they are equal (=(3/23)(x+12))
