You're close, but what you're actually doing is using PEMDAS in reverse.



%281%2F8%29%287m-7%29=%282%2F5%29%284m-4%29%2B8 Start with the given equation.


%287%2F8%29m-7%2F8=%288%2F5%29m-8%2F5%2B8 Distribute.


Multiply EVERY term by the LCD 40 to clear any fractions.


35m-35=64m-64%2B320 Multiply and simplify.


35m-35=64m%2B256 Combine like terms on the right side.


35m=64m%2B256%2B35 Add 35 to both sides.


35m-64m=256%2B35 Subtract 64m from both sides.


-29m=256%2B35 Combine like terms on the left side.


-29m=291 Combine like terms on the right side.


m=%28291%29%2F%28-29%29 Divide both sides by -29 to isolate m.


m=-291%2F29 Reduce.

Answer:

So the solution is m=-291%2F29 which approximates to m=-10.034.
