1. Add 2y to both sides.
subtract 20 from both sides, and finally, divide both sides by 2.

2. With only one equation, all you can do is express x in terms of y or y in terms of x. You cannot solve for both simultaneously unless you have a second independent equation.

For y in terms of x, add 2y - 20 to both sides and you get
(3/2)x -20 = 2y
Now divide both sides by 2 and you end up with
y = (3/4)x - 10
