You move all the x's too one side 
7x-5x=5
the you subtract 5x from 7x 
7x-5x=2x
so now it is 
2x=5 
you need to get x alone so you divide x by 2 and you have to do it to both side so you divide 5 by 2 
x=5/2 
Exvited
[tex]7x=5+5x \\ \\ 7x - 5x = 5 \\ \\ 2x = 5 \\ \\ x = \frac{5}{2} \\ \\ [/tex]

The final result is: x = 5/2 or x = 2.5.
