answer:

-2x + 9 or -2 which is what the question asks

step-by-step explanation:

  • we have to combine like terms which means terms that are similar
  • in this, only 5x and -7x are like terms since both have x with them
  • 9 will stay the same since it does not have a like term

5x + 9 + (-7x) = __x + 9

-2x + 9

  • therefore, -2 goes in the blank

Combined the like terms . -2x+9 goes in the blank, bc 5-7=-2
