If y + 3y + 5y = −18, then what is the value of y?

If y + 3y + 5y = −18, then what is the value of y?

Detailed Explanation

When terms with the same variable are in the same equation, they can be combined:

y + 3y + 5y = −18

9y = −18

y = -18 ÷ 9 = -2

y + 3y + 5y = −18

9y = −18

y = -18 ÷ 9 = -2
