0.10(5000) = 500
0.15(10,000) = 1500
total commission on 15,000 = (150 + 500) = 2,000
3+6x+3x+ 6 = 180
9x + 9 = 180
9x = 171
x = 19

Answer:
Helen is 24; Robert is 39
Step-by-step explanation:
If Helen's age is x, Robert's age is x + 15. We can write:
x + x + 15 = 63
2x + 15 = 63
2x = 48
x = 24
This means that Helen's age is 24 and Robert's age is 24 + 15 = 39.
