Question

Last week, Donnell practiced the piano 3 hours longer than Marcus. Together, Marcus and Donnell practiced the piano for 11 hours. For how many hours did each young man practice the piano?​

Answer 1

Answer:Marcus=4 Donnell=7

Step-by-step explanation:11-3=8

8÷2 =4

4+3=7 hours used by Donnell

Remaining 4 hours is used by Marcus

Answer 2

4 hours and 7 hours

Explanation:

Marcus = x hours

Donnell = x + 3 hours

Total = 11 hours

• x + x + 3 = 11
• 2x + 3 = 11
• 2x = 8
• x = 4

So Marcus practiced 4 hours and Donnell practiced 7 hours
