Question

Nancy is 5 yrs younger than her brother stan last year she was half as old as he was how old are they both

Answer 1

Answer: 11 and 6

Explanation:

I think this is it because she is 5 years younger and last year she was half of his age so he was 10 then you have to add another year to their age because that was last year, 5+1=6, 10+1=11. but im not completely sure so if you can wait for someone else or if you agree go ahead and answer it.

Answer 2

We'll call the ages n and s

Nancy is 5 yrs younger than her brother Stan

n = s - 5

Last year she was half as old as he was

n - 1 = (1/2) ( s - 1 )

We substitute for n

s - 5 - 1 = (1/2) (s - 1)

2s - 12 = s - 1

s = 11

n = s - 5 = 6

Answer: Nancy is 6, Stan is 11

Check:

Clearly they're five years apart. Last year they were 5 and 10, half, good.
