Simplify the following expression:
Simplify the following expression:
In order to solve this question, remember that we can perform the addition and subtraction operations when we have the same variable.
However we are limited when we have several different variables.
Note that in this exercise that we have three variables:
which has no variable
and which both have the variable
and with the variable
Therefore, we can only operate with the y variable, since it's the only one that exists in more than one term.
Rearrange the exercise:
Combine the relevant terms with
We observe that this is similar to one of the other answers, with a small rearrangement of the terms:
Given that we have no possibility to perform additional operations - this is the solution!
