Question

How do you solve ((a+1)/3)+((a+1)/4)=9 ?

Answer 1

i dont know the answer is correct or not..! but this ques can be solved like this..
[(a+1)/3]+[(a+1)/4]=9,
\[\frac{ 4a+4+3a+3 }{ 12 }=9\],
7a+7=108
7(a+1)=108
a+1=15.42
a=14.42

Answer 2

that method works, (if you round correctly)

Answer 3

but i'm suppose get 12

Answer 4

hey iam not able to catch my mistake ..!! whats it.??

Answer 5

\[ \frac{a+1}3+\frac{a+1}4=9\\
4\frac{a+1}{12}+3\frac{a+1}{12}=9\\
7(a+1)=12\times9\\
a+1=\frac{12\times9}7\\
a=\frac{12\times9}7-1\\
\quad=14.43\]
