We just add like terms:

  • 7x+2x-x=8x
  • -9y
  • -7+5=-2

Put them all together to give you:

[tex]8x-9y-2[/tex]

Answer:

  • 10x - 9y - 12

Step-by-step Solution:

  • (7x - 9y) + (2x - 7) - (-x + 5)
  • => (7x - 9y) + (2x - 7) + (x - 5)
  • => 7x - 9y + 2x - 7 + x - 5
  • => (7x + 2x + x) - 9y + (-7 - 5)
  • => 10x - 9y + (-12)
  • => 10x - 9y - 12

Hence, the simplified expression is 10x - 9y - 12.
