(3x - 5) + (5x + 1)
Simplify it in polynomials

______________________________

 - When there is more then 1 variable then you must combine them, (If possible.) In this case we have 2 variables, so to combine them you just have to add them together.

Equation at the end of Step 1:

 - We do this because we need to get to 1 leftover number. So to do this, you just subtract/add the numbers by each other. In this case we have to add -5 by 1.

So your answer is .
