Let x be the original pieces of pizza.
Janet ate 14 pieces/slices
Remaining pizza: 2/9 (x)

Equation:
     14 + (2/9)(x) = x

Multiply each term by LCD 9:
     (9)(14) + (9)(2/9)(x) = (9)(x)
     126 + 2x = 9x
     126 = 9x - 2x
     126 = 7x
      7x/7 = 126/7
      x = 18

ANSWER:  There were 18 pieces of pizza.

Check:
14 + (2/9)(18) = 18
14 + 4 = 18
18 = 18 (true)
