Answer 1

let no. of deer be x
x/2 +3x/4 +9=x
solve this equation

Answer 2

Let the number of deer be x

deer grazing => 1212xx

Deer playing =>34(12=>34(12x)x)

=> 3838xx

1212x+38x+38x+9=xx+9=x

1212x+38x+38x−x=−9x−x=−9

4x+3x−8x84x+3x−8x8=−9=−9

4x+3x−8x=−724x+3x−8x=−72

7x−8x=−727x−8x=−72

−x=−72−x=−72

x=72x=72

Answer : 72
