Answer:

(c) 5x and 3x, and 4 and 1

Explanation:

Like terms have the same variable(s) to the same power(s).

The terms of this expression are ...

  • x^3: variable x, power 3
  • 5x: variable x, power 1
  • -3x: variable x, power 1
  • 3y: variable y, power 1
  • 4: no variable
  • -1: no variable

The like terms are {5x, -3x}, which have the x-variable to the first power, and {4, -1}, which have no variable.
