  • 4
  • -x
  • -1

Like Terms:

  • -5x and -x
  • 4 and -1

Coefficients:

  • The coefficient of -5x is -5.
  • The coefficient of -x is -1.

Constants:

  • 4
  • -1

You simplify the expression by combining like terms:

-5x + 4 - x - 1 = -6x + 5

(7b - 4) + (-2b + a + 1) = 7b - 4 - 2b + a + 1 = 5b + a - 3
