**Reiny**, Monday, May 24, 2010 at 8:03pmSo it is

[x/(2-x)]/(x-4) = -4/(x-4) ?

Where does the third equality come from ?

Can you see why brackets are absolutely necessary here?

ok, first multiply both sides by x-4 to get

x/(2-x) = -4

now multiply both sides by 2-x

x = -4(2-x)

x = -8 + 4x

-3x = -8

x = 8/3

Lastly, what does "...if it has no equation state so. simply with necessary " mean ?
