i can not get number one! "How old will John be when his age is twice his sister's age?" so confusing
Current ages are J=20 and S=20/4=5.
If J is 4 times older: 4*S=J
In how many years, lets say x years, will J be twice as old as S:
2*(S+x)=J+x
2S+2x=J+x
2S+x=J; S=5 and J=20
10+x=20
x=10
which means J will be twice as old as S in 10 years.
J+10=30.
