You can put this solution on YOUR website! 5x -7 = 8/7x - 5 +7
---
5x - 7 = (8/7)x +2
---
(35/7)x -(8/7)x = 9
---
(27/7)x = 9
27x = 63
x = 63/27
x = 7/3

You can put this solution on YOUR website! subtract 8/7x
5x-8/7x-7=-5+7
add 7
35/7x-8/7x=9
27/7x=9
divide by 27/7
x=9/(27/7)
invert and multiply
x=9*7/27
x=63/27
x=2 1/3
