Question

Identify the like terms in the following expression 12y+9x+7x

Answer 1

12y + 9x + 7x

The like terms are 9x and 7x. This is because they both have the x variables attached to the number. This means that you can add only 9x and 7x (not 12y because it isn't a like term) together like normal numbers (except with an x at the end so you would get: 12y + 16x

Hope this helped!

Answer 2

the like terms are 9x and 7x, if you are told to simplify, you write, "12y+16x"
