(see below)

Explanation:

Given
#color(white)("XXX")color(red)(X=[(4,1),(-2,6)])#
and
#color(white)("XXX")color(blue)(Z=[(-1,3),(0,2)]#
then
#color(white)("XXX")color(red)(X)-color(blue)(Z) = [(color(red)4-color(blue)(""(-1)),color(white)("XX"),color(red)1-color(blue)3),(color(red)(""(-2))-color(blue)0,,color(red)6-color(blue)2)]#

#color(white)("XXXXXXX")=[(5,-2),(-2,4)]#
