interpretation: x/2+y/6-z/4
Input:
x/2 + y/6 - z/4
Alternate form:
1/12 (6 x + 2 y - 3 z)
Real root:
z = 2 x + (2 y)/3

Answer:
Pounds of apple used = 10,078.20
Pounds of taffy = 144.80
Step-by-step explanation:
Assume :
x = pound of taffy mixture
y = pounds of apple mixture
Total :
x + y = 10,223 - - - (1)
Proportion of apple to taffy
x / y = 1 / 69.6
Cross multiply :
y = 69.6x
(1) becomes :
x + 69.6x = 10223
70.6x = 10223
x = 10223 / 70.6
x = 144.80169
Put x = 144.80169 in
y = 10223 - x
y = 10223 - 144.80169
y = 10078.19831
Pounds of apple used = 10,078.20
Pounds of taffy = 144.80
