Summary. Hello dear, there are 8 white rabbits, 3 more black rabbits than 2 times the white rabbits, and 19 black rabbits.

There are 8 white rabbits, 3 more black rabbits than white rabbits, and how many black rabbits there are.

Hello dear, there are 8 white rabbits, 3 more black rabbits than 2 times the white rabbits, and 19 black rabbits.

The column formula is as follows: because the black rabbit is twice as many as the white rabbit, three more, and the white rabbit is eight, so the black rabbit is 2 8 + 3 = 19.

Solution: Let the black rabbit have x, the white rabbit has x+27, x+27=4x

4x-x=27

3x=27x=27÷3

x = 9 white rabbits = x + 27 = 9 + 27 = 36 Answer: There are 36 white rabbits and 9 black rabbits.

Set up a black rabbit. There are x only. There are 3x white rabbits. Equation: 3x-x=16 x=8 3x=24 Answer: There are 24 white rabbits and 8 black rabbits.

Solution: Because there are 16 more white rabbits than black rabbits, and the number of white rabbits is 3 times that of black rabbits.

So 3 times the black rabbit minus the black rabbit is equal to 16

This results in a 2x black rabbit equal to 16

The black rabbit is equal to 8

So the white rabbit is equal to 16 plus 8

It is equal to 24 Answer: 24 white rabbits and 8 black rabbits.

96 (only), A: There are 96 white rabbits and black rabbits;

2) 72-24 = 48 (only), A: 48 fewer white rabbits than black rabbits

Solution: If there are x black rabbits, then the white rabbits are 4x.

4x+x=25 means 25 black rabbits and white rabbits.

5x=25x=5 Finally, x=5

Answer: 5 black rabbits.

There are x black rabbits.

x+4x=25, x=5, so there are 5 black rabbits.

Let the black rabbit be x, the white rabbit is 4x, x+4x=25, and the solution is x=5, and there are 5 black rabbits.

5 pcs. Suppose there are x black rabbits, then there are 4x white rabbits, x+4x=25, x=5
