Answer:
1 pound and 28 crowns is equivalent to 7 dollars.
Explanation:
Let the dollars be x , crowns be y and pound be z.
To find = 1z + 28y = ? (value in dollars)
5 dollars and 35 crowns is equivalent to 7 pounds
...[1]
![z=\frac{5}{7}x+5y](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B5%7D%7B7%7Dx%2B5y)
4 dollars and 4 pounds is equivalent to 56 crowns
![4x+4z=56y](https://tex.z-dn.net/?f=4x%2B4z%3D56y)
...[2]
Using value of from [1] here in [2]:
![x+\frac{5}{7}x+5y=14y](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B5%7D%7B7%7Dx%2B5y%3D14y)
![\frac{12}{7}x=9y](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B7%7Dx%3D9y)
![y=\frac{4}{21}x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B21%7Dx)
Now:
![z=\frac{5}{7}x+5y](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B5%7D%7B7%7Dx%2B5y)
![z=\frac{5}{7}x+5\times\frac{4}{21}x](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B5%7D%7B7%7Dx%2B5%5Ctimes%5Cfrac%7B4%7D%7B21%7Dx)
![z=\frac{35}{21}x=\frac{5}{3}x](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B35%7D%7B21%7Dx%3D%5Cfrac%7B5%7D%7B3%7Dx)
1z + 28y = ?
![\frac{5}{3}x+28\times \frac{4}{21}x](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7Dx%2B28%5Ctimes%20%5Cfrac%7B4%7D%7B21%7Dx)
![=\frac{5}{3}x+\frac{16}{3}x=7x](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B3%7Dx%2B%5Cfrac%7B16%7D%7B3%7Dx%3D7x)
