I think of a number, add 5, multiply by 11, square root the number, then subtract 3+2. The answer is 6 what is the starting number?????¿¿¿¿

Let N be the number....so we have
√[(N+5)*11] - (3+ 2) = 6
√[(N+5)*11] - 5 = 6 add 5 to both sides
√[(N+5)*11] = 11 square both sides
(N + 5)*11 = 121 divide by 11 on both sides
N + 5 = 11 subtract 5 from both sides
N = 6
So, the strating number is 6
$${\mathtt{a}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{11}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{a}}}}{\mathtt{\,-\,}}{\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}} = {\mathtt{6}} \Rightarrow {\mathtt{a}} = {\mathtt{7}}{\mathtt{\,-\,}}{\mathtt{55}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{a}}}}$$
