I'm sorry but this equation still makes no sense to me and I still do not know how to solve it.

Where did the 3/2 even come from?

one x plus one-half x equals one and one-half x which can be written as (3/2)x.  If I use a decimal representation, then I'd have:
 
1.0x + .5x = 542
 
1.5x = 542
 
Better?
