Simple. Just get x to stand alone.
20x=53 Subtract 3 from both sides.
20x=2
x=2/20 Divide 20 on both sides.
x=1/10 Simplify.

I'll show you how to do these problems so that you'll learn how to do the rest of your problems
20x+3=5
Subtract 3 from both sides of the equation.
20x = 2
Divide both sides by 20
x = 2/20
x = 1/10
________________________________
4x=9
Add x to both sides.
5 = 9 + x
Subtract 9 from both sides.
49 = x
5 = x
