DUE TO SOME PROBLEM PLUS SIGN IS NOT VISIBLE SO I TAKE HELP OF NEGATIVE SIGN,SO UNDERSTAND IT
1) let sam's age=x
joan's age=y
then
x-(-y)=48
& y=3(x-(-8))
on solving these equations we get x=8,y=40
2)let liza's age=x
lino's age= y
then
x=2y
& x-5-(-y)-5=32
on solving these equations we get
x=28,y=14
3) Let toni's age=x
nitoy's age=y
then
x=y-(-4)
& x-(-5)=2(y-(-5)-3)
on solving these equations we get
x=9,y=5
