Answer:
19 birds
Step-by-step explanation:
First, I wrote my two equations:
5.5x +8.5y = 291.5
x + y = 41
Next, I got the variable y by itself in the second equation. Subtract x to get y = -x + 41. Then, I substituted what y equaled into the first equation. It should look like this: 5.5x + 8.5(-x+41) = 291.5. Distribute 8.5 to get 5.5x -8.5x + 348.5 = 291.5. Subtract 5.5x and 8.5x to get -3x. It should look like this: -3x + 348.5= 291.5. Subtract 348.5 from 291.5 to get -57. Now, you should have -3x = -57. Divide -3 from both sides, to get x = 19. So, there are 19 birds. If you want to go even further, 41-19= 22, which means there are 22 cats. Hope this helped!

Answer:
Step-by-step explanation:
Let the required amount is x.
<u>Alcohol content is same at the end:</u>
- x*0.17 + 4*0.2 = (x + 4)*0.19
- 0.17x + 0.8 = 0.19x + 0.72
- 0.19x - 0.17x = 0.8 - 0.72
- 0.02x = 0.08
- x = 0.08/0.02
- x = 4
