Answer:

  • 17x - 5

Step-by-step explanation:

  • 9(x - 5) + 8(x + 5) =        open parenthesis
  • 9x - 45 + 8x + 40 =       collect like terms and simplify
  • 17x - 5

[tex]\\ \sf\longmapsto 9(x-5)+8(x+5)[/tex]

[tex]\\ \sf\longmapsto 9x-45+8x+40[/tex]

[tex]\\ \sf\longmapsto 9x-8x-45+40[/tex]

[tex]\\ \sf\longmapsto x-5[/tex]
