Define a variable ** Let x represent the number of erasers Gabriel collected.
How many erasers did Celine collect? ** Celine collected 2*x erasers.
How many erasers did Julian collect? ** Julian collected 2*x*2=4*x erasers.
How many erasers did Gabriel, Celine and Julian collect? ** In total, Gabriel, Celine and Julian collected x+2*x+4*x=7*x erasers.
Write an equation ** 7*x=35
Simplify ** x=<<5=5>>5
How many erasers did Celine collect? ** Celine collected 5*2=<<5*2=10>>10 erasers.
