-7%2F8=m-3%2F8 Start with the given equation.


8%28-7%2Fcross%288%29%29=8%28m-3%2Fcross%288%29%29 Multiply both sides by the LCD 8 to clear any fractions.


-7=8m-3 Distribute and multiply.


0=8m-3%2B7 Add 7 to both sides.


-8m=-3%2B7 Subtract 8m from both sides.


-8m=4 Combine like terms on the right side.


m=%284%29%2F%28-8%29 Divide both sides by -8 to isolate m.


m=-1%2F2 Reduce.

Answer:

So the solution is m=-1%2F2 which in decimal form is m=-0.5.
