Alice-4

John-8

Dad-40

Step-by-step explanation:

1) using the information we know if j is John's age and a is Alice's age and d if dad's age:

2a=j

d=5j=5 (2a) = 10a

(a+2) + (d+2) + (j+2) = 58

2) substitute the d and j for the equivalent terms using a so there is only one variable, Alice's age:

(a+2) + (10+2) + (2a+2) = 58

3) combine like terms and isolate the variable and you should get your answer.
