x=number of hours marcus played on piano so the equation could be x+(x+3) =11 
 Solve:
x+(x+3) =11
2x+3=11
2x=8
x=4 which means marcus played for 4 hours and because darnell practiced three hours longer darnell practiced for 7

17. x= the price of cupcakes
the equation could be 16+24x=52
Soution: 
16+24x=52
24x=36
x=36/24
x=1.50 so cupcakes cost $1.50 each
