weight of a truck is 4 times than weight of a car. if their weight together 6075kg,?

4n = weight of truck

n = weight of car

total weight = 6075

required: find the weight of each.

4n+n = 6075

5n = 6075

n = 6075/5

n = 1215

(truck) 4n = 4(1215)

4n = 4860

(car) n = 1215

=)

weight of car be x

weight of truck is 4x

x+4x=6075

5x=6075

x=1215

weight of car is 1215kg

weight of truck is 4860kg
