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

[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
