Answer :
Step-by-step explanation:
Consider the age of billy as x
and sally be y
so first equation is
y = x+5
x+y = 53
these are the two equations and then just solve them simultaneously
to get the ages
x-y = -5
x+y = 53
2x = 48
x = 24
Hence billy's age is 24 years
and Sally is five years elder so 29 years is sallys age
Answer:
it is very easy. just do 53:2 because there are to persons(26,5). and now you need to take the half of 5 which is 2,5. this you need to do because there are two persons again. now for the older person you do 26,5+2,5=29. and for the junger person 26,5-2,5=24. sally is 29 years old. Billy is 24 years old
