4x + 6 + 3 =

please explain step by step

4xboxes + 6+3 = what do your think?

How many xboxes do you have? Still just 4
How many numbers do you have? 6+3=9

so the answer must be
4x + 9
------------------------------------------------------------
You can only add or subtract like terms. The terms are like if they have exactly the same letters and those letters must be raised to exactly the same powers.
Try this one
5x+3y-2y+7+9 =

Thank You Melody.
