Answer:

2M + 3 hrs

Explanation:

Lisa spent doing her mathematics homework = M hrs

the amount of time spent watching television was 3 hours more than twice the time she spent doing her mathematics homework.

lisa spent on watching television = 2M + 3 hrs

Total time spent on these two activities = M + 2M + 3

= 3M + 3 hrs

3 M + 3 = 30

=> 3M = 27

M = 9
