For fractions (like 1/2x), you just multiply both sides by the inverse of whatever fraction of x you have.
For example 1/5x = 4
(5/1)1/5x = 4(5/1)
5 times 1/5 is 1, so you're left with x = 20
This is probably confusing you, I'll just let your teacher do it :/

Keep in mind if you're going to ask for help with equations that contain fractions, you need to write it differently. I understood what you were trying to say, but others may not.
1/5x = 4
This reads:
1 divided by 5x equals 4. This would mean that x = .05
Your equation should have been set up in any of these ways:
x(1/5) = 4
(1/5)(x) = 4
Or, as you become more familiar with algebraic equations containing variables, you will come to know that multiplication is distributive, so you could have simply wrote it as x/5, because 1*(x) = x.
