2x+7x

what is the answer to this

9x

Step-by-step explanation:

X is an unknown variable so just leave x as it is

Because the (2x) and the (7x) are being multiplied together they are almost seen as their own category of things

Think about having two bananas in a bowl. I just threw in seven more to get a total of nine bananas in the bowl.

It's the same thing when you have a variable right next to a number! add them together as if they are alike terms.

2+7=9 therefore your answer should be 9x

Answer: 9x

because you add both numbers and both letters (letter must be the same) together.
