How old is nina now?Answer by AnlytcPhil(1276)   (Show Source): You can put this solution on YOUR website!```Billy is 44, which is twice as old as Nina was x years ago, which was N-x 44 = 2(N-x) x years ago, Billy, who is now 44, was 44-x, which is as old as Nina is now, N. 44-x = N The system of equations is 44 = 2(N-x) 44-x = N Solve that system by substitution and get x = 11, N = 33 Nina is 33. Checking: 11 years ago Billy was 44-11=33, which is Nina's present age, and Nina was 33-11=22. So Billy, at 44, is now twice as old as Nina was 11 years ago at age 22. Edwin```
