ana and christion collect stamps.together they have 500 stamps in their collection. ana has 150 fewer stamps then christian.how many stamps does christian have
Lets represent Ana and Christion using the Letters A and C a+c=500 c=a+150 now substitute c for a+150 back into the first equation a+a+150=500 a+a=350 2a=350 Divide by two a=175 Now that we know annie has 175 all we do is subtract that from the total (500) C=325 Sure enough, 175 is 150 less than 325 Hope that helped, send me a message if you need clearing up :D
