Ok, this is going to look strange, but there's no way to show the actual work from by homework, so deal with it.

-4x-7=49

(add 7 to each side and you get...)

-4x=56

(divide each side by -4 and you get...)

x=-14

(check if this is correct [it is]; i just did math with letters)

No you did math with numbers in place of letters. Try again.

Who attempted to do math without any numbers anyway?

Re-read the last 6 pages you will see.

Firstly, x=2. Secondly, you just did math with letters.

Face it and embrace it.

No I replaced a letter with a number and then did the math.

But it's symbolic notation.

What do you call this:

We use it in maths, though.

It's called pie. It stands for a number 3.14... with a bunch of numbers after the .14, and with out the number value you wouldn't be able to use it in a math problem.

There's a bunch of symbols used in math that aren't numbers.

Prove it.

I can't believe we're even having this debate

Honestly, neither can I.

Ikr?

Also, 2x+2=8. Wardogg, solve this; It's simple.

I'm not doing your fucking homework for you. I don't have to do homework anymore. Also I guarantee that "x" in the equation stands for a number.

I can't believe we're even having this debate

idk my bff jill?

Quit trolling the teenage chat rooms. It starts to effect your speech after a while.

Jill must have many BFFs...

Too bad your not one of them. I bet that makes you feel sad and depressed. See your razor blade for help.

How fun.

Actually I'm bored.

Seriously? I just spent an entire week in math, doing it without any numbers, you need to understand the algebra in order to do math, and algebra is math with letters.

No Algebra is math with letters that stand for numbers. Therefore you can't do math with letters.

x = 2 not 12. 2x2=4 4+1=5. It's algebra.

Firstly, x=2. Secondly, you just did math with letters.

Face it and embrace it.

Actually, given that no other constraints have been placed on x, the solution is x = 2 or -2.

Also:

And yet again we prove that math with letters doesn't work. You have to replace them with numbers to do the math.

BTW I got As in Algebra and Trig. It was Geometry that kicked my ass every year. Theorems and postulates, WTF is that shit.
