Question

180x + 4 = 64

Answer 1

180 x = 60
60/180 = x
1/3 = x

Answer 2

This is similair to your other questions. Instead of having two variables on one side you only have one. So first we'll get the variable term by itself by taking away 4 from 64.

180x = 64-4 = 180x = 60

So now we get the variable (x) by itself by dividing since the original equation is multiplication. 60/180 = .33 so x = 1/3 (Turned into a fraction)
