### Instruction:
 Celine collected twice as many erasers as Gabriel did. Julian collected twice as many erasers as Celine did. If they collected 35 erasers in total, how many erasers did Celine collect?


### Response:
 Soit x le nombre de gommes que Gabriel a collectées.
Celine a collecté 2*x gommes.
Julian a collecté 2*x*2=4*x gommes.
Au total, Gabriel, Celine et Julian ont collecté x+2*x+4*x=7*x gommes.
7*x=35
x=<<5=5>>5
Celine a collecté 2*x=2*5=10 gommes.
