Answer 1

Answer:

There are 5 cats and 6 children

Step-by-step explanation:

Let x = number of cats

Let y= number of children

Counting heads gives 11

X+Y = 11 .....eq1

Counting feet gives 32

Cats has 4legs,child has 2 legs

4X + 2Y=32 ....eq2

X = 11 - Y

Put in eq2

4(11-Y) + 2Y = 32

44 - 4Y + 2Y=32

12=2Y

Y=12/2=6

Y=6= Children

Put Y=6 in eq2

X + 6=11

X=11-6=5

X= 5 = cats
