Final Answer:
The simplified expression is 16e - 9.
Step-by-step explanation:
Combine the exponential terms:
Since 6e and 10e both have the same base (e), we can simply add their coefficients:
6e - 9 + 10e = (6 + 10)e - 9
Simplify:
Combining coefficients: 16e - 9
Therefore, the simplified expression is 16e - 9.
