# If $\begin{vmatrix} x & x \\ 1 & x \end{vmatrix} = \begin{vmatrix} 3 & 4 \\ 1 & 2 \end{vmatrix}$write the positive value of x.

Can you answer this question?

Toolbox:
• The above given two matrices are equal,hence their corresponding elements should be equal.
$\Rightarrow x=3,x=4,x=2.$
So the positive value of x=3,4,2
