You can put this solution on YOUR website!
x = granola y = apples
x + y = 6........1
210x + 424y = 1688.....2

Multiply 1 by 424
424x + 424y = 2544
210x + 424y = 1688
Subtract
214x = 856
x = 856/214
x = 4
Substitute x = 4 into 1
x + y = 6
4 + y = 6
y = 2
So 4 pounds of Granola and 2 pounds of apples
