Answer:


x = 10

Explanation:

Given:


(x -1)/(3) = k \text{ where } k = 3

Solving for
x:


(x -1)/(3) = k \text{ where } k = 3\\ (x -1)/(3) = 3 \\ (x -1)/(3) \cdot 3 = 3 \cdot 3 \\ x -1 = 9 \\ x -1 +1 = 9 +1 \\ x = 10

\large (x - 1)/(3) = k \: and \:k = 3

__________________________________________


\large\bf{\underline{Putting\: the\:value\:of\:k}}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
⟹ \large (x - 1)/(3) = 3

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
⟹\large {x - 1 = 3 * 3}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
⟹\large{x = 9 + 1}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
⟹\large{x = 10}

\large\bf{\underline{Hence}}


\huge{⟹x = 10}
