The answer is correct
the max weight shall be 80
mass of small box = 5 lb. ( and there are x number of boxes )
Mass of big box = 12 lb. ( and there are y number of boxes )
adding them up shall be less than or equal to 80 ( as the shelf can withstand up to 80 lbs. )
And the minimum number of boxes shall be equal to 4
If we take the x as the number of boxes, then x would be greater than or equal to 4

Answer: I believe the answer to this question is: X= 1/5.
Ok so let’s write out the problem
4x+6=-x+1
We first want to get the x’s on one side and the numbers on the other
4x+6=-x+1
+x. +x
5x+6=1
Now we want to get the 6 over
5x+6=1
-6. -6
5x=5
Divide by 5 to get the x alone
X is equal to 1
