.
R=Renato's age; D=Domeng's age
.
R=D-3 Use this to substitute for R below.
.
R-6=(2/3)(D-6) Substitute for R from above.
D-3-6=(2/3)(D-6)
D-9=(2/3)D-4
D-5=2D/3
3D-15=2D
D-15=0
D=15 ANSWER 1: Domeng is 15 years old.
.
R=D-3=15-3=12 ANSWER 2: Renato is 12 years old.
.
CHECK:
R-6=(2/3)(D-6)
12-6=(2/3)(15-6)
6=2/3(9)
6=6
