Question

Y + 3y + 5y = -18 what is the value of y

Answer 1

y = -2

Explanation:

Step 1: Combine like terms.

• 
  `(y+3y+5y)=-18`
• 
  `9y=-18`

Step 2: Divide both sides by 9.

• 
  `9y/9=-18/9`
• 
  `y=-2`

Step 3: Check if solution is correct.

• 
  `-2+3(-2)+5(-2)=-18`
• 
  `-2-6-10=-18`
• 
  `-18=-18`

Therefore, y = -2.
