-6 -6
Step-by-step explanation:
Hi there!
The time Jamaal spends in practicing the guitar is represented by X.
The time he works in his homework is represented by Y.
The sum of both numbers must be bigger than 45 (minutes). Therefore, we can set up the following inequality:

The sum of both equals or is bigger than 45 minutes.
To find the time Jamaal spends on practicing the guitar (which was represented by X), we must subtract the time he does his homework (which was represented by Y) from both sides.

The time Jamaal spends practicing the guitar is equal to or bigger than 45 minutes minus the time he spends on his homework.
