Simon and Jimmy had 167 stamps
altogether. Simon gave 4/7 of his stamps to Trina, and Jimmy gave 37 stamps to Trina. Simon and Jimmy had the same number of stamps left. How many stamps did Jimmy have in the beginning?

I need a formula

• Math -

let the number of stamps that Simon has be x
then the number of stamps that Jimmy has be 167-x

Simon gives 4/7 of his to Trina, so he has (3/7)x left
Jimmy gives 37 to Trina, so he has 167-x - 37 or 130-x left

but now they have the same

solve : (3/7)x = 130 - x
hint: multiply both sides by 7 etc.

• Math -

72

Pretty sure it's 76.

• Math -

Simon started with 91 and Jimmy started with 76. Trina has 89 when it is done.

• Math -

76
