# A farmer has chickens and pigs. His animals have 53 heads and 142 legs between them. How many chickens and how many pigs does the farmer have? *​

There are 35 chickens and 18 dogs.

(Note: Unless you mean pigs and not dogs, the number of pigs the farmer have can not be determined. But if it's a typo error, then you can figure it out. Thanks.)

Step-by-step explanation:

Total Number of Heads = Total Number of Animals

Given:

Total heads or animals (combined chickens and dogs): 53 Total legs: 142

Let the animals be:

Chickens: xDogs: y

Equation (1):

x + y = 53

x = 53 - y  (chickens)

Let the legs be:

Chickens: 2xDogs: 4y

Equation (2):

2x + 4y = 142

Solve the system by substitution when x = 53-y:

2x + 4y = 142

2(53-y) + 4y = 142

106 - 2y + 4y = 142

Find y, the number of dogs:

2y = 142 - 106

2y/2 = 36/2

y = 18  (number of dogs)

Find x, the number of chickens:

x = 53-y

x = 53 - 18

x = 35  (number of chickens)

Check:

Number of heads or combined chickens and dogs:

x + y = 53

35 + 18 = 53

53 = 53  (True)

Number of legs:

2(35) + 4(18) = 142

70 + 72 = 142

142 = 142  (True)

1. 30 pesos or Php 30

2.240 pesos or Php 240

Step-by-step explanation:

1st question= 200+ (3x50)=350 pesos

350-320(the money he spent)= 30 pesos

2nd question=(2x240)+(2x140)= 480+280=760 pesos

1000(money she has)- 760(the money she spent)= 240 pesos

18 pigs and 35 chickens

Step-by-step explanation:

Let x  = number of pigs and   y  = number of chickens

then    4x + 2y    =   142   ---   and x + y =  53

2x + 2y     = 106       /  multiply    { x +y  = 53} by 2

2x + 0y     =   36

x             =   18 pigs

x + y   =   53

18 + y  =  53

y =   35  chickens
