Question

Simplify: 14x - 14 - 2 {x-[3x +(13x-3) ] } + 28
please show work

Answer 1

First work with the insides. Thus we should work with 3x+(13x-3) first. This gives 16x - 3.
Substituting what we've got back to the whole equation, it now looks like this:

14x - 14 - 2 {x-(16x-3) } + 28

Now lets work with the insides again by simplifying (1)x-(16x-3), which should give the following: -15x-3. Substituting what we've got back to the whole equation, it now looks like this:

14x - 14 - 2 (-15x -3) + 28

Now we need to yet again work with the insides:
-2 (-15x -3)
= 30x +6

We substitute this back into the equation and get:
14x - 14 +30x +6 + 28

Now simplifying the equation further, we get the following after some simple algebra:
44x + 8
