Answer 1

Hi Darla,

It looks like you've set up the equation accurately representing the scenario provided. Are you needing help with solving for x?

If so, remember that in solving for a variable we are trying to isolate that variable (i.e., get it by itself). So, think about what is happening to x currently (is it being multiplied, divided, etc.?), and how do we undo those operations.

For example, if you have something like 2y + 5 = 10 we would first subtract 5 from both sides, and then divide both sides by 2 to isolate y.

2y + 5 = 10

- 5 -5

2y = 5

/2 /2

y = 2.5

Let us know what you wind up and I can confirm or help further as needed.
