The answer is "x + 4x = 35; 7 large stones and 28 small stones"
Step-by-step explanation:
Please find the complete question in the attached file.
Let
[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]
Users want to use four small stones for each big stone:
[tex]Y = 4x[/tex]
solving the equations system:
[tex]x + y = 35\\\\y = 4x[/tex]
we find:
[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]
