Hey! :)
So first before anything else, let's establish our variable.
Any number = n
Now, let me tell you some definitions you'd need to know for this problem.
Divided by = /
Subtract = -
The result = whatever was previously stated
So we can use n and create the equation:
n/-4 - 7
*Note: Here's another way to write this:
![-(n)/(4) - 7](https://img.qammunity.org/2020/formulas/mathematics/middle-school/btzp064kuiuy2q5m073x1s0qiz72bc3a1y.png)
Please let me know if you have any questions! :)
