the ages of elsa, edna and ellie are consecutive intergers. the sum of their ages is 126. what are their ages?

Question

hartnn · Answer

let the age of elsa be x
since the ages are consecutive, ages of other 2 are x+1 and x+2
sum = 108
so 
x+x+1+x+2 = 108
can u solve further ?

anonymous · Answer

sory not 108 its 126

hartnn · Answer

anonymous · Answer

im sooooo confused..if the sum of their ages is 114 instead of 126 for their age..how do i solve for x if i dont know what im even looking for? i got 39 40 and 41....i dont know what im doing wrong!!:(

anonymous · Answer

the new some is 114 becuase i got the 126 problem wrong and they gave me a different problem

hartnn · Answer

now 114 ?
x+x+1+x+2 = 114
combine like terms
x+x+x=3x
1+2=3
so 
3x+3=114
3x=111
x=37
got this?
so ages are 37,38,39

anonymous · Answer

if the previous  sum was 114, why do i get 111 though?

hartnn · Answer

because its $\huge3x+3=114$
so when u subtract 3 from both sides, u get 
$\huge3x+3-3=114-3=111$
