CJ, KJ, and AJ collect stamps. CJ has 5 more than twice the number of stamps that KJ has, and KJ has half as many as AJ. If the three boys have 930 stamps all together, how many stamps does AJ have?

Define a variable ** Let x represent the number of stamps for AJ
How many stamps does KJ have? ** KJ:x/2 stamps
How many stamps does CJ have? ** CJ:5+2(x/2)=5+x
Write an equation ** Total:x+(x/2)+5+x=930
Combine like terms ** (5/2)x+5=930
Subtract 5 ** (5/2)x=925
Divide by (5/2) or multiply by (2/5) ** x=925(2/5)=370 stamps
