x=6

Explanation:

5/3-2/x=8/x|color(blue)(*x)
5/3color(blue)(*x)-2/cancel(x)cancel(color(blue)(*x))=8/cancel(x)cancel(color(blue)(*x))
5/3x-2=8|color(blue)(+2)
5/3xcancel(-2color(blue)(+2))=8color(blue)(+2)
5/3x=10|color(blue)(*3/5)
cancel(5/3color(blue)(*3/5))*x=2cancel(10)color(blue)(*3/cancel(5))
x=6

x=6

Explanation:

First, ensure that all terms with x in the denominator are on the same side. This entails adding 2/x to each side:

5/3cancel(-2/x+2/x)=8/x+2/x

Since the terms on the right have a common denominator, we can add:

5/3=(8+2)/x

5/3=10/x

Multiply each term by the term diagonal to it:

5x=10(3)

5x=30

Divide each side by 5:

(cancel5x)/cancel5=30/5

x=6

5/3-2/x=8/x

5/3cancel(-2/x)cancel(+2/x)=8/x+2/x

5/3=10/x

5/3*x=10/cancelx*cancelx->5/3x=10

cancel(5/3)x*cancel(3/5)=10*3/5

x=6

Hope that helped!
