SOLUTION: [ [2+m] / [2-m] ] = 3/4 i dont know if you set it up where it looks like 2+m-3/2-m-4=0 or work through to get a common denom and leave the variable on one side help please??????

You can put this solution on YOUR website!
%282%2Bm%29%2F%282-m%29=3%2F4 Start with the given equation.


4%282%2Bm%29=3%282-m%29 Cross multiply.


8%2B4m=6-3m Distribute.


4m=6-3m-8 Subtract 8 from both sides.


4m%2B3m=6-8 Add 3m to both sides.


7m=6-8 Combine like terms on the left side.


7m=-2 Combine like terms on the right side.


m=%28-2%29%2F%287%29 Divide both sides by 7 to isolate m.

Answer:

So the solution is m=-2%2F7
