Explanation:

Please find the complete question in the attached file.

Let

`x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35`

Users want to use four small stones for each big stone:

`Y = 4x`

solving the equations system:

`x + y = 35\\\\y = 4x`

we find:

`x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\`
