Answer:

x=3, y=15

Step-by-step explanation:

We substitute 5x for y, getting 5x = -3x + 24. We add 3 x to both sides, and have a equation like this: 8x = 24. Divide by 8 on both sides, and we know that x = 3. Since y is 5x, y is 5*3, which is 15.

r-ruslan [8.4K]

Answer:

  • 20 chickens
  • 25 rabbits

Step-by-step explanation:

Let r represent the number of rabbits the farmer has. Then 45-r is the number of chickens. The total number of legs is then ...

  4r +2(45-r) = 140

  r +45 = 70 . . . . . . . . divide by 2 and simplify

  r = 25 . . . . . . . . . the number of rabbits

  45 -r = 20 . . . . .  the number of chickens

The farmer has 20 chickens, and 25 rabbits.
