Question 1176532: Carl and dennis are brothers. The sum of their age is 29. In 6 year time Carl will be the same age as Dennis was 3 years ago how old is Carl and how old are both the brothers Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Carl and Dennis are brothers. The sum of their age is 29.
c + d = 29
In 6 year time Carl will be the same age as Dennis was 3 years ago
c + 6 = d - 3
c - d = -3 - 6
c - d = -9
how old is Carl and how old are both the brothers
use elimination with these two equations
c + d = 29
c - d = -9
----------
2c + 0 = 20
c = 20/2
c = 10 yrs is Carl's age
then, obviously, 19 is Dennis' age
