Math problem

Solve: 5/(x8)5/x = 40/(x^28x)
How would this be solved?

Multiply both sides of the equation by
x(x8) 
Please stop changing posting names. It does you no good when working with volunteers when you try to trick them. It is difficult enough to work through these with students who are stuck in their thinking, but much more so when those students pretend to be new at the work.
Thanks. 
x^28x = x(x8) which is LCD
so
5(x)  5(x8) = 40
x  x + 8 = 5
There is no solution. x can be anything 
Thank You Damon I understand now.
