Answer
notebooks are 2.39 each
Work Step by Step
6 notebooks and 2 binders = 23.52
3 notebooks and 4 binders = 25.53
$6x+2y=23.52$
$3x+4y=25.53$
$6x+2y=23.52$
$2(3x+y = 11.76)$
$3x+y=11.76$
$3x+4y-(3x+y)=25.53-11.76$
$3x+4y-3x-y=25.53-11.76$
$3y=13.77$
$3y/3 = 13.77/3$
$y=4.59$
$3x+4y=25.53$
$3x+4*4.59=25.53$
$3x+18.36=25.53$
$3x = 7.17$
$3x/3=7.17/3$
$x=2.39$
