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

Answer 2

=14x-16{x-[3x+13x-3]=14x-16{x-16x-3}=14x-16x+256x+48=254x+48

Answer 3

kwo is wrong x-(16x-3) -> -15x + 3

Answer 4

TheMind why -16 { }..
it is -2 { }

Answer 5

ooppsss.... yes, Coolsector is right about that

Answer 6

yes a little misspell i guess

Answer 8

44x+8

Answer 9

44x+8 is the final answer?

Answer 10

Yes, and all the work is shown above in my previous comment.
However, if you want to solve for x, then it would be -8/44, which gives -2/11 or -0.18181818

Answer 11

ok thank you

Answer 12

I am assuming, however, that 0 = 44x + 8 initially.
Just so you know...
