1. 2x + 4 = 3(x – 2) + 1














2. 4(x + 3) = 3x + 17














3. 3x + 4 + 2x = 5(x – 2) + 7



4. 2(1 + 5x) = 5(2x – 1)














5. –18 + 15x = 3(4x – 6) + 3x














6. –10 + 5x = 5(x – 3) + 5

Please, do not post more than 1 or 2 questions at a time.  Out of courtesy I will address one of your six questions here:

2x + 4 = 3(x – 2) + 1

You are to solve this for x.

1) perform the multiplication:     2x + 4 = 3x - 6 + 1
2) combine like terms:                4+6-1 = x
3) solve for x:                              x = 11
4) check:  Is 2(11) + 4 = 3(11-2) + 1 true?
   Is 22+4 = 33-6 true?  NO.  Try again, looking for the mistake:

2x + 4 = 3(x – 2) + 1  =>   2x + 4 = 3x - 6 + 1
                                                  4 = x - 5
                                                  9 = x

Check:  Is 2(9) + 4 = 3(9-2) + 1 true?  Is 18+4 = 22 true?  YES.
The solution to #1 is  x = 9  (answer).

Submit your other questions separately, please.
