Step-by-step explanation:

let deers be x and visitors be y

so x+y = 39 ( they have 1 head )

y=39-x

4x+2y = 132(deers have 4 legs and visitors have 2 legs)

2(2x+y)=132

2x + y = 66

hence , 2x + 39-x = 66

x= 27

so, y= 12

So, 27 deers and 12 visitor

Let,

• Number of visitors = x

• Number of deer = y

Given,

• (1)     x + y = 39 [∵ 1 head per visitor + 1 head per deer]

• (2)    2x+4y = 132 [∵ visitors having 2 legs + deer having 4 legs]

Applying (1) in (2):

[tex]\sf\implies {2x + 4(39 - x) = 132}[/tex]

[tex]\sf\implies {2x + 156 - 4x = 132}[/tex]

[tex]\sf\implies {4x - 2x = 156 - 132}[/tex]

[tex]\sf\implies {2x =24}[/tex]

[tex]\sf\implies {x =\dfrac{24}{2}}[/tex]

[tex]\sf\implies {x =12}[/tex]

Applying value of x in (1):

[tex]\sf\implies {12+y =39}[/tex]

[tex]\sf\implies {y =39-12}[/tex]

[tex]\sf\implies {y =27}[/tex]

Therefore:

[tex]\boxed{\bold{\sf{Number \ of \ visitors = 12}}}[/tex]

[tex]\boxed{\bold{\sf{Number \ of \ deer = 27}}}[/tex]
