The value of $x$ is $32$ .

Explanation of Solution

Given information : The equation is $x-12=20$ .

Concept used : First we have to solve the equation then the $x$ substitute by the value of $x$ in the equation to check.

Calculation :

  $\begin{array}{l}x-12=20\\ \Rightarrow x=20+12\\ \Rightarrow x=32\end{array}$

Thus, the value of $x$ is $32$ .

Verification:

Left hand side,

  $\begin{array}{l}x-12\\ =32-12\\ =20\end{array}$

Right hand side $=20$

Therefore, Right hand side = Left hand side.
