Answer:

  x = 5

Step-by-step explanation:

Perhaps you want to solve for x the rational equation ...

  (2+5x)/(3x) = (7x -18 +2x)/(3x)

Multiplying by 3x and collecting terms, we have ...

  2 +5x = 9x -18

  20 = 4x . . . . . . add 18-5x to both sides

  5 = x . . . . . . . . divide both sides by 4

The solution is x=5.
