Then the last one for today...thank you all very much
Louis is 6 years older than Karen, but Karen is 4 years older than Heidi, The sum of their ages is 53. How old is Heidi?.
Thank you once again, to all the ones who are helping me today!!
l+k+h=(h+10)+(h+4)+ h = 3h + 14
3h + 14 = 53
3h = 39
heidi is 13 (which means karen is 17 and louis is 23 )
WOW!!!...great way of solving this!!!..Tank you very very much!!
