%281%2F8%29%287m-7%29=%282%2F5%29%284m-4%29%2B8

Since two of the terms have fractions in front,
let's write 8 as the fraction 8%2F1

%281%2F8%29%287m-7%29=%282%2F5%29%284m-4%29%2B8%2F1

The fractions have denominators 8, 5, and 1
so the LCD = 40 so we multiply through every
term by 40%2F1



 
 5            8        


5%287m-7%29=16%284m-4%29%2B320

35m-35=64m-64%2B320

35m-35=64m%2B256

-29m=291

m=%28291%29%2F%28-29%29

m=-291%2F29
