Jewel is 7 years old and John is 16 years younger than Dave. One year ago, Dvae's age was twice the sum of Jewel's and John's ag
ivanzaharov [21]

Answer:

Jewel is 7 years old

John is 1 year old

Dave is 17 years old

Step-by-step explanation:

From the question we are told that:

Jewel age is J=7 years

John age J'=(D-16)years

Dave's age a Year ago

 D-1=2(J-1+J'-1)

So that Dave.s age this Year could be

 D=2((J-1)+(J'-1))+1

Simplifying Equation for Dave's age we have

 D=2((7)-1+(D-16)-1)+1

 D=2(6+D-15)+1

 D=2(D-9)+1

 D=2D-18+1

 D=17 Years

Dave is 17 years old

Therefore

Johns age is

 J'=(D-16)

 J'=17-16

 J'=1year old

John is 1 year old
