Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

  • [tex](y+3y+5y)=-18[/tex]
  • [tex]9y=-18[/tex]

Step 2: Divide both sides by 9.

  • [tex]9y/9=-18/9[/tex]
  • [tex]y=-2[/tex]

Step 3: Check if solution is correct.

  • [tex]-2+3(-2)+5(-2)=-18[/tex]
  • [tex]-2-6-10=-18[/tex]
  • [tex]-18=-18[/tex]

Therefore, y = -2.
