Question

Solve the following simultaneous equations using graphical method
$4x=y-5$
$y=2x+1$

Answer 1

$4x=y-5$

$x$	$0$	$2$	$-2$
$y$	$5$	$13$	$-3$

$y=2x+1$

$x$	$0$	$2$	$-2$
$y$	$1$	$5$	$-3$

Plotting both the equations on graph, as shown, $(x,y)=(-2,-3)$ is the solution of the given pair of equations.
