Answer/Explanation:

First way:

Step 1: Cross-multiply.


  • (5)/(x-3) = (10)/(x)

  • 5 * x = 10 * (x-3)

  • 5x = 10x - 30

Step 2: Subtract 10x from both sides.


  • 5x - 10x = 10x - 30 - 10x

  • -5x = -30

Step 3: Divide both sides by -5.


  • (-5x)/(-5) = (-30)/(-5)

  • x = 6

Second way:

1.
(5)/(6-3) = (10)/(6)

2.
(5)/(3) = (10)/(6)

3.
(5)/(3) = (5)/(3)
