Joseph had 265 stamps. David had twice as many stamps as Joseph and Davis had 179 more stamps than Jamal. How many stamps did Jamal have?


Solution:
Joseph: 265 stamps.
David:  twice as many stamps as Joseph - so 530 stamps
David:  179 more stamps than Jamal - so #Jamal's  stamps + 179 stamps = #David's stamps.

So #Jamal's stamps = #David's stamps - 179 stamps = 530 stamps - 179 stamps = 351 stamps

Jamal has 351 stamps
