Britton, Ignac and Delroy have some stamps each. Britton has 2/7 as many stamps as the total number of stamps Ignac and Delroy have. Delroy has 26 less stamps than Britton. Ignac has 95 more stamps than Britton. How many stamps must Ignac give to Britton and Delroy in total so that they each have the same number of stamps?

Question

oobleck · Answer

so, what do we know?
b = 2/7 (i+d)
d = b-26
i = b+95
Now, if Ignax gives x to Britton and y to Delroy,
i-(x+y) = b+x
i-(x+y) = d+y
Solve all that and you find that Ignac must give
23 to Britton
49 to Delroy.
