D-Dylan
A-Ashley
J-Jacob
K-Kyle
S-Shelby

1. D+13=66, Solve for D to get Dylanâ??s current age, Shelbyâ??s current age when multiplied by three the product is greater than 66, however the information on Shelby in this number is not necessary, use it to check your work when you've found Shelby's age through #5.
2. J+A=101, See #4.
3. K+32=A, When you have found A, plug it in and solve for K.
4. A-53=J, Put the equation so it is A=something or J=something and then plug in the â??somethingâ?? into #2, that way there will only be one variable, then solve for it. Do the same for the other variable or plug in the one you already found and solve.
5. 2S=D-9, when heâ??s found Dylanâ??s age from #1, plug it in and solve for S to get Shelbyâ??s age.

Hope this helps.
