I assume it is not 8x/(10x-2). Spacing helps to make this clear.
8/10x - 2 = 5x + 3/7x
To get rid of the denominators, multiply both sides by 70.
56x -140 = 350x + 30x
Combine terms.
-140 = 350x + 30x - 56x = 324x
solve for x. 8x/10x-2 = 5x+3/7x
i don't know how to get the x squares out of the equation!
