Question 1069006
x sold for 6
y sold for 8
x+y = 14 subtract x from both sides:
y = 14-x
Next:
6x+8y = 92 substitute for y
6x+8(14-x) = 92 
Distributive property of multiplication:
6x+112-8x = 92
-2x = -20
Divide both sides by -2, and remember -/- = +
x = 10
y = 14-x = 4
--------------------
Check:
(10*6)+(4*8) = 92 Correct
