7x+3 - 2x-1 + 7
5x 3x
(*5x and 3x is denominators...and i guess 1 for 7*)

I don't see an equals-sign, so it's not an equation.
Do you mean:
(7x+3)/5x = (2x-1)/3x + 7
... or something like that?
Assuming that's it, multiply by 15x to get rid of all the denominators:
(7x+3)/5x = (2x-1)/3x + 7
3(7x+3) = 5(2x - 1) + (15x)(7)
21x + 9 = 10x - 5 + 105x
14 = 94x
x = 14/94 = 7/47

If (5x) & (3x) are denominators, then what are the numerators for each?
If this is an equation, then where is this sign: =?
Lastly, what does the phrase, " ...and i guess 1 for 7*" mean?

This isn't an equation. There's no equal sign. Solution is impossible. Correct this.

Are you using math in a desperate effort to find meaning in your meaningless life? It won't work.
