Answer:
-3/2
Step-by-step explanation:
Let x = the integer:
2x^2 - 18 = 9x
2x^2 - 9x - 18 = 0
Now either factor that or use the quadratic formula if you're lazy like me.
x = -3/2 and 6, so x must be 6 because it has to be an integer.
yes, because 46.2/6 = 7.7 ounces and 107.8/14 = 7.7 ounces

X + y = 3500 -------------- (1)
x - y = 2342 --------------- (2)
(1) + (2):
2x = 5842
x = 2921 -------------- Sub into (1)
x+ y = 3500
2921 + y = 3500
y = 3500 - 2921
y = 579
----------------------------------------------
Answer: x = 2921, y = 579
----------------------------------------------
