Answer:
weight of large box = x kg=18.25kg
weight of small box =y kg=15.5kg
Explanation:
weight of large box = x kg
weight of small box =y kg
2 large boxes and 3 small boxes has a total weight of 83 kilograms.
2x+3y=83--------- eq 1
4 large boxes and 8 small boxes has a total weight of 197 kilograms.
4x+8y =197 -------eq 2
multiply eq 1 with -2
-4x-6y =-166
now add both equations
-4x-6y=-166
4x+8y=197
______________________
2y= 31
y=15.5
substitute value of y=17 in eq 1
2x+3y=83
2x+3(15.5)=83
2x+46.5=83
2x =36.5
x=18.25
weight of large box = x kg=18.25kg
weight of small box =y kg=15.5kg
hope this helps :)
