Simple problem:

When simplifying 3(x-6) they subtracted 3 instead of multiplied by 3.
3(x-6) should be 3x-18.
Now when you simplify:
3x-18+4x+12-6x
Which is x -6 =0
Or x =6

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 1/3 of one section of the fence.
sergejj [24]

Answer: The \frac{1}{12} part of fence is painted.

Explanation:

It is given that we have a 32-foot fence around a square garden. There are 4 equal sections. You paint 1/3 of one section of the fence.

Since the fence divided in 4 equal parts, therefore the value of one section in fraction is  \frac{1}{4}.

After that we paint \frac{1}{3} of the one section.

Since one section is equal to \frac{1}{4}, therefore \frac{1}{3} of the one section \frac{1}{4} is,

\frac{1}{4} \times \frac{1}{3}=\frac{1}{12}

Therefore, the \frac{1}{12} part of fence is painted.
