2 answers:
Nancy: 5 Stan: 10
5 is 5 years
younger then Stan
And 5 is twice as
young as 10
Answer:
Nancy is 6 years old and Stan is 11 years old now.
Step-by-step explanation:
Let the present age of Stan be x.
Then age of Nancy = y
x - y = 5
Last year she was twice as young as he was
Age of Nancy last year = y-1
Age of Stan last year = x-1
2 × (y-1)= x-1
2y -2 = 5 + y -1
y = 6
x = y + 5 = 6 + 5 = 11
Nancy is 6 years old and Stan is 11 years old now.
