Chicken and rabbit in the same cage: chicken and rabbit in the same cage have 35 heads and 94 feet. How many chickens and rabbits are each asked (use the method of binary linear equation, and write the solution)?

Chicken and rabbit in the same cage: chicken and rabbit in the same cage have 35 heads and 94 feet. How many chickens and rabbits are each asked (use the method of binary linear equation, and write the solution)?

Both the chicken and the rabbit have only one head, but the chicken has two horns and the rabbit has four
X + y = 35 1
2X + 4Y = 94 2
By subtracting two times of Formula 1 from formula 2, we can get y = 12
Then we substitute 1 to get x = 23

1/4x+5+1/2【x-（1/4x+5）】-5+40=x

1/4x+5+1/2【x-（1/4x+5）】-5+40=x
arrangement:
1/4x+1/2x-1/8x-5/2+40=x
De denominator
2x+4x-x-20+320=8x
3x=300
x=100

4X + 12 = 80 to solve the equation
Format:
4x =
=

4x=80-12
4x=68
x=68÷4
x=17
