x/2x/x4=4/x4=4x^2/2
check this please

Please check your typing, and use brackets to avoid ambiguity.

in the problem there are no brackets
x over x minus x/over x4 equal 4 over x4 solve each rational equation if it has no equation state so. simply with necessary
Please help me 
So it is
[x/(2x)]/(x4) = 4/(x4) ?
Where does the third equality come from ?
Can you see why brackets are absolutely necessary here?
ok, first multiply both sides by x4 to get
x/(2x) = 4
now multiply both sides by 2x
x = 4(2x)
x = 8 + 4x
3x = 8
x = 8/3
Lastly, what does "...if it has no equation state so. simply with necessary " mean ?
