Tiffany practiced 5 hours in previous week to the last week.
Given that:
- Tiffany practiced her bassoon last week a total of 7 hours.
- Her practice last week was 2 hours more than her time of practice in previous week.
To find: How many hours did Tiffany practice the previous week?
Equation formation and calculation:
Duration of practice in last week = 2 hours + Duration of practice in previous week
x = 2 + y,
where x = Duration of last week = 7 hours
and y =Duration of practice in previous week
Thus, we have:
[tex]x = 2 + y\\7 = 2 + y\\y = 7 - 2\\y = 5[/tex]
Thus, y = Duration of practice in previous week = 5 hours.
Thus, Tiffany practiced 5 hours in previous week to the last week.
