Question

Find the solution of lines :$\begin{array}{c}x+y=4\\ 2x-3y=3\end{array}$

Answer 1

$x+y=4$

$2x-3y=3$

$x+y=4\Rightarrow 2x+2y=8\Rightarrow 5y=5\Rightarrow y=1$

$2x-3y=3\Rightarrow 2x-3y=3\Rightarrow x=3$

From the figure it is clear that

Sol is $x=3,y=1$

Sol is $x=3,y=1$

$\therefore (x,y)=(3,1)$
