12x+20-4+8x=6-2x

20x+16=6-2x

22x+16=6

22x=-10

x=-0.45

uhoh. Doesn’t look right. I’m no good at math >_< atleast you get my drift...or what not to do. edit! yay! I feel less dumb now. I was like d'oh you're a senior and you're having a hard time with basic algebra!?

12x+20-4+8x = 6-2x

20x + 16 = 6 – 2x

22x = -10

x = -10/22 which is -5/11

I AM 1000000000……………..% SURE!!

HOPE IT HELPS! =]

(12x+20)-(-4+8x)= 6-2x

NEXT: add/subtract like-numbers

4x+24= 6-2x

THEN: add to one side

24=6+2x

THEN: SOLVE

24=6+2x

-6 -6

18= 2x

/2 /2

9 = x

I hope that helps.

Good luck!
