.... You can't do those still in Algebra?...

Might be his first lesson of it or something, this is usually the first thing in Algebra you learn, just simple rearranging and stuff.

Gl with it, this is basically the only maths I can remember how to do with ease seeing as it doesn't require me to remember of those formulas :p
 
I know all about distributive property...I just have problems showing my work...when I do show my work I get the wrong answer...but I can get the answer straight from my head...which takes few min to do in my head but the work showing is my problem like 8 steps..
 
6x + 84=4x -124 X=-104

12x + 108=8x + 200 X=23

-16x + 216= -8x -216 X=-52

5x - 168= -4x - 924 X=-84

18x + 138 = 15x + 12 X=-41 and a third

3(-6x + 18)= -6x -138 X=16

-5(-3x + 43) =6x -638 X=47

4(6x - 15) = 6(3x + 62) X=72

3(9x + 4) =2 (8x + 105) X=18

4(2x + 210) = 3(3x-109) X=1167

Did it in my head...might be a slight chance one is wrong...i also may have misplaced a negative sign in some ^.^;
 
I think those tight jeans are somehow responsible for your math troubles. :(

Say hello to someone that failed 7th grade math.
 
I can get correct answers but showing the work is the only problem..
 
lol i did this like 5 years ago.. good luck when you get into college algebra ahahahahahahah
 
Here are all the correct answers (I'm 98% sure), because I checked them all in the solver program on my calculator. The ones with a tick next to them are correct. I made a error in question 4, because I added instead of subtracting, but I have re-written that one correctly.

Here are all the answers, with working out.

Oh shit, this is easy, I can probably do them all, one sec I need some paper.

Reserved.

EDIT:

Code: 
1.) X = -104

2.) X = 23

3.) X = 0

4.) X = -84

5.) X = -42

6.) X = -16

7.) X = -75.666667 (Not sure if this one is correct)

8.) X = 72

9.) X = 18

10.) X = 1167

Hopefully these are right. I'm unsure about #7 though.

I also suggest you get one of these:

They run you around 100$ USD, but they are amazing calculators.

I wish I could've done this, but my handwriting is too messy. This should help him though.
 
hey u can easily check your own answers by substituting what you got for x for x.
EX.
6x + 84=4x -124
6(-124)
 
Aww sorry i used to be good with algebra but over the christmas holiday i forgot!!! lols ^.^ sorry cant help

cheers
