Question

Can someone help I don’t know if you can see but I need help on all the problems.

Answer 1

Number of oxen = 16

Number of chickens = 6

Explanation:

Let,

x be the number of oxen

y be the number of chickens

According to given statement;

x+y = 22 Eqn 1

4x + 2y = 76 Eqn 2

Multiplying Eqn 1 by 4

4(x+y=22)

4x+4y=88 Eqn 3

Subtracting Eqn 2 from Eqn 3

(4x+4y)-(4x+2y)=88-76

4x+4y-4x-2y = 12

2y = 12

Dividing both sides by 2

`(2y)/(2)=(12)/(2)\\y=6`

Putting y = 6 in Eqn 1

x + 6 = 22

x = 22 - 6

x = 16

Hence,

Number of oxen = 16

Number of chickens = 6
