Q1) x+y=4 ,3x-2y=4.determinant METHOD FIND d

\:  \bullet \bf{x + y = 4 \:  \:  \: ...(1)}

\:  \bullet \bf{3x - 2y = 4....(2)}

\: \\   \implies \underline{ \bf{by \: using \: determinant \: form}}

\:  \:  \: \underline{ \boxed{ \bf \color{red} \: to  \: find \to \: the \: value \: of \: d}}

\:   \huge \underline{ \boxed{ \bf{solution}}}

A=\left[\begin{array}{cc}1&1&4\\3&-2&4\\\end{array}\right]\\

\:  \implies \displaystyle \tt{(1 \times  - 2) - (1 \times 3})

\:  \implies \displaystyle \tt{( - 2) - (3)}

\:  \implies \displaystyle \tt{ - 5}

\:  \: \bullet  \underline { \boxed{ \bf \color{brown} \: the \: value \: of \:  determinant (d) \: is \:  - 5}}
