Nina is 4 years older than Sam. Next year Nina is 3 years older. How old are they?
Answered by John
Nina = sam + 4

(Nina +1) = (Sam +1) +3

Sam + 4 + 1 = Sam + 4

5 = 4 for a final answer which is a false statement; therefore there is no solution. Something is wrong with the problem as written.

That what I thought. Thank you.

4*S + 1 = 3*S + 3 ====> S = 2.


Answer. Sam is 2 years old. Nina is 4*2 = 8 years old.
