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.
