Answer:
Trina is 56 years old
Step-by-step explanation:
If Duane is 6 years older than his brother, who just turned 14, we are adding 14+6, which is 20.
If trina is 4 years less than TRIPLE Duanes' age, then we first find triple of Duanes' age 20 x 3, which is 60. Then we find 4 less than 60, which is 56.
