Question

timmy and tommy are two boys whose ages add up t0 23.timmy is 5 years older than tommy . how old are thay ? answer plz

Answer 1

Hey Freind!

Let us assume that age of Timmy is x yrs.
Then we can conclude that age of Tommy is =
(23 -x) yrs.

Now we know that Timmy is 5 years older than Tommy, therefore,
x = 5 + (23-x)
x = 5 + 23 - x
x + x = 28
2x = 28
x = 28/2
x = 14 Answer. (Age of Timmy)

Hence age of Tommy is 23 - x = 23 - 14 = 9 yrs.

Answer 2

$let \: timmy \: age \: = x \\ so \: tommy \: age \: = (23 - x) \\ we \: know \: that \: timmy \: is \: 5 \: years \: older \: than \: tommy \\ atq..... \\ x = 5 + (23 - x) \\ x = 5 + 23 - x \: (transfering \: x \: to \: left \: side) \\ x + x = 5 + 23 \\ 2x = 28 \: (transfering \: 2 \: to \: right \: side) \\ x = \frac{28}{2} \\ x = 14 \\ therefore \: timmy \: age \: is \: 14 \: years \\ tommy \: age \: = 23 - x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: 23 - 14 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: 9 \: years$
