Hi,

John is 11 years older than Sam's age highlight_green%28x%29

Question states***

  x(x+11) = 180

  x^2 + 11x - 180 = 0

 (x + 20)(x-9) = 0,   x = 9,Sam's age   (negative solution thrown out for unit measure)

CHECKING our answer*** John is 20

  9•20 = 180

Wish You the Best in your Studies.
