a pig and a bear weight 70 kg

What is the weight of each animal?
Answers
Step-by-step explanation:
Let weight of one bear be x
weight of one pig be y
weight of one fox be z
Weight if two bears = x + x = 120 kg
=> 2 x = 120
=> x = 120 / 2
=> x = 60 kg ( Ans)
Weight a pig and a bear => y + x =70 kg
=> y + 60 = 70
=> y = 70 - 60
=> y = 10 kg ( Ans)
Weight a bear, a fox and a pig => x + y + z = 90 kg
=> 60 + 10 + z = 90
=> z + 70 = 90
=> z = 90 - 70
=> z = 20 kg ( Ans)
