### Instruction:
 Celine alikusanya mara mbili ya idadi ya madaftari aliyokusanya Gabriel. Julian alikusanya mara mbili ya idadi ya madaftari aliyokusanya Celine. Ikiwa walikusanya jumla ya madaftari 35, Celine alikusanya madaftari mangapi?


### Response:
 Hebu x iwe idadi ya madaftari aliyokusanya Gabriel.
Celine alikusanya madaftari 2*x.
Julian alikusanya madaftari 2*x*2=4*x.
Jumla ya madaftari walioyakusanya Gabriel, Celine, na Julian ni x+2*x+4*x=7*x.
7*x=35
x=<<5=5>>5
Celine alikusanya madaftari 2*x=2*5=10.
