I have a horrible text book thats rather new and a ton of the answers are wrong in the book.
My teacher gives us 924085093 ways to work 1 problem. so its gets confusing. I am stuck on this one, and have probably been over thinking it and just stressing over it. I am guessing i am missing one silly step. Can someone tell me what it is please?

Thanks in advance

5x+ 6 = 3(x-4) +4 = 5

Nobody can answer your question, until you first define the meaning of your pronoun "this".

Ask your teacher for an errata sheet.

Clearly, you have an excellent teacher. I'm envious. :mrgreen:


5x+ 6 = 3(x-4) +4 = 5

No equation contains more than one equal sign. As typed, this "equation" makes no sense.

Please proofread and correct your typing; then, somebody here can help you.

If you've already typed it exactly as it appears in your book, then ask your teacher to proofread and correct it.

5x + 6 = 3(x - 4) + 4

The solution is x = -29

5x + 6 = 5

The solution is x = -1/5

3(x - 4) + 4 = 5

The solution is x = 13/3

5x + 6 + 3(x - 4) + 4 = 5

The solution is x = 7/8

5x + 6 - 3(x - 4) + 4 = 5

The solution is x = -17/2

5x + 6 = 3(x - 4) + 4 + 5

The solution is x = -9/2

5x + 6 = 3(x - 4) + 4 - 5

The solution is -19/2

There are other possibilities, for what the posted "equation" is supposed to be.

By the way, if you had followed our forum guidelines, you would have shown some work. (Check out the post titled, "Read Before Posting".)

Chances are good that, by inspecting your work, I would have been able to figure out any typographical errors and/or mathematical mistakes, and you'd already be on your way by now.

Got the message ? 8-)
