%28-2%2F5%29%2810x-25%29+=+8x%2B4

First, multiply both sides of the equation by 5 to get rid of the fraction.

5%2A%28-2%2F5%29%2810x-25%29+=+5%2A%288x%2B4%29 ---> -2%2810x-25%29+=+5%2A%288x%2B4%29

-20x+%2B+50+=+40x%2B20

Group like terms as follows,

-20x+-+40x+=+-+50+%2B+20

Solve,
-20x+-+40x+=+-+50+%2B+20

-60x+=+-30


Divide both sides by -60 to isolate x:

%28-60x%29%2F-60+=+%28-30%29%2F%28-60%29

x+=+1%2F2
