Answer:

[tex]\boxed{\boxed{\sf x=-9}}[/tex]

Step-by-step explanation:

[tex]\sf 6x-7+2x=-79[/tex]

Combine like terms:

  • [tex]\sf 6x+2x-7=-79[/tex]
  • [tex]\sf 8x-7=-79[/tex]

Add 7 from both sides:

  • [tex]\sf 8x-7+7=-79+7[/tex]
  • [tex]\sf 8x=-72[/tex]

Divide both sides by 8:

  • [tex]\sf \cfrac{8x}{8}=\cfrac{-72}{8}[/tex]
  • [tex]\sf x=-9[/tex]
