Answer:
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.
