Combine like terms. 3y + y + 6y a. 10y b. 8y c. 9y-y d. 2y

First off,like terms are value with the same unknown.

For example,in the equation 2x+3y+5y+4x,

The like terms would be 2x and 4x, with the same unknown x,
and the other like terms would be 3y and 5y with the same unknown y.

In this case (3y+y+6y), as they all have unknown y, they all are like terms.

To combine,we can simply add them together:


Therefore the answer is A. 10y.

Hope it helps!

Iam not sure , but probably 750 or 7.5
