Question 1 Report

If $| \begin{matrix} 5 & 3 \\ x & 2 \end{matrix} |$ = $| \begin{matrix} 3 & 5 \\ 4 & 5 \end{matrix} |$ , find the value of x

Answer Details

$| \begin{matrix} 5 & 3 \\ x & 2 \end{matrix} |$ = $| \begin{matrix} 3 & 5 \\ 4 & 5 \end{matrix} |$
10 - 3x = 15 - 20
-3x = 15 - 20 - 10
-3x = -15
x = 5
