$[9,13]=[x+2y,4x+1] rArr x+2y=9, &, 4x+1=13.$
$rArr x+2y=9, 4x=13-1=12 rArr x+2y=9,x=3.$
$rArr 3+2y=9 rArr 2y=9-3=6 rArr y=3.$

$:. x=3, y=3.$

$x=3,y=3$

$"equating corresponding components"$

$4x+1=13rArrx=3$

$x+2y=9rArr2y=6rArry=3$

How do you find the values of x and y given [(9, 13)]=[(x+2y, 4x+1)][(9, 13)]=[(x+2y, 4x+1)]?
