Solution:

Note that:

  • Given equation: -8(5 - 3n + 7n) = -40 + 24n - 56n

Simplify both sides:

  • -8(5 - 3n + 7n) = -40 + 24n - 56n
  • => -40 + 24n - 56n = -40 + 24n - 56n

Since both sides are equal, this equation has infinite solutions.
-8(5-3n+7n)= -40+ 24n -56n
-(8•5)-(-8•3n)-(8•7n)=-40+ 24n -56n
-40+ 24n -56n =-40+ 24n -56n
