Question

how do I combine x + 2x + 1/2x and get 7/2x?

Answer 1

You mean to add : x , 2x and \(\large{\frac{1}{2}x}\) ? @vanessa32

Answer 2

or it is : \(\large{\frac{1}{2x}}\) ?

Answer 3

assume all your x-terms are apples and all your constants are oranges. meaning that you can add all apples together and all oranges together...
