Let’s take T for Trevon and R for Riggs.
T = 7 years older than R which can be written as T = R + 7
Their combined age is 49.
Therefore, T + R = 49
We need to find Trevon’s age (T.)
We can substitute R + 7 for T in the equation
T + R = 49.
We have:
R + 7 + R = 49
Now solve.
2R + 7 = 49
2R = 42
R = 21
We have found Riggs’ age which is 21.
Add 7.
Trevon’s age is 28.
