Question

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

Answer 1

Answer:

y = -2

Step-by-step explanation:

Add up the coefficients of the three y terms:

(1 + 3 + 5)y = -18.

Then (9)y = -18.

Dividing both sides b y 9, we get:

y = -18/9, or y = -2.

Answer 2

Answer:

y=-2

Step-by-step explanation:

In order to find out the value of y, we have to isolate the y. In order to do that, we first have to combine all like terms and we do that by adding the numbers with variables together.

1y+3y+5y=9y

9y=-18

Now we have to get the y by itself so we divide 9 on both sides of the equation because once we do that, we can cancel out the 9.

9/9=1 -18/9=-2

So the answer is y=-2.
