Hi there!
To figure out the value of x, we can use a proportion. Here's the proportion we'd use: 15/7 + x = 9/x. Next, we'll need to cross-multiply in order to get an equation that we are able to solve: 9(7 + x) = 15x. Then, we'll distribute the terms: 63 + 9x = 15x. Lastly, we'll subtract 9x from each side and divide to find the value of x: 6x = 63 | x = 10.5.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Substitute the values. 
Follow PEMDAS and multiply and divide first.

Andy money doubled. i.e. $3000
The second day made profit. $3000 + $165
Later he lost $238
The expression is:
2*1500 + $165 -$238
Good luck.
