Question

Combine like terms 3Y plus Y plus 6Y

Answer 1

10y. That is the answer

Answer 2

3y+y+6y

Notice that all these terms have the 'y' variable in them, meaning they are all like terms.

'y' by itself acts as a One, when adding it to other like terms.

3y+6y=9y

Then, add the singular y to the equation = 9y+y=10y
