Answer:

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

Sara wants to find the input value that produces the same output for the functions represented by the tables.

Ivahew [28]

Unfortunately, there are no given tables. To solve the given problem, the functions which fits the values in the tables must be known. This process is called modeling. One could test if the values fit a linear model, a quadratic model, or any other model. After knowing the functions, equating the two functions, would yield the input value that gives the same output.
