Solution:
1. Let J be Jamal's age.
2. Todd is 10 years older than Jamal:
T = J + 10
3. The sum of their ages is 64:
T + J = 64
4. Substitute T = J + 10 into the equation T + J = 64:
(J + 10) + J = 64
5. Simplify and solve for J:
2J + 10 = 64
2J = 54
J = 27
6. Substitute J = 27 back into the equation for T:
T = 27 + 10 = 37
So, Jamal is 27 years old, and Todd is 37 years old.
