i understand what i did wrong now
2007-09-30 18:12:06 · update #1
8x + 4x = 23 + 1
12x = 24
x = 2

If solving for x:
1) Write the original equation.
2) Add 4x to both sides so that you have like-terms on both sides of the equation.
3) Add 1 to both sides so that you have like-terms on both sides of the equation.
4) Combine like-terms.
5) Divide.
6) Final answer with given information.
1) 8x - 1 = 23 - 4x
2) 8x + 4x - 1 = 23 -4x + 4x
3) 8x + 4x - 1 + 1 = 23 + 1
4)12x = 24
5) 12x/12 = 24/12
6) x = 2
Final answer: x = 2
hope this helps!

8x-1=23-4x
8x+4x-1=23
8x+4x=23+1
12x=24
x=2

1. Add 4x on both sides: 8X+4X -1 = 23 -4X+4X,
12x -1 = 23
2. Now Add 1 on both sides: 12X -1+1 = 23+1
12X=24
3. Divide by 12 on both sides: 12X/12 = 24/12
X=2
So answer is {2}

yes x equals 2
4x+8x-1=23-4x+4x -8x+8x-1=23-4x-8x
12x-1=23 -1=23-12x
1+12x-1=23+1 -23-1=-12x
12x=24 -24=-12x
**** this didnt come out right
fu kid you should try doing the problem twice before asking yahoo for help

8x-1=23-4x
--> add 4x to each side:
12x -1 = 23
--> add 1 to each side:
12x = 24
--> divide each side by 12:
x = 2

8x -1 = 23 - 4x :
You have to get the X's on one side, so u do this:
8x + -4x and u get 4x so u put it on the 8's side cuz it is bigger
4x - 1 = 23
Then u plus one to each side:
-1 = 23
+1= +1 equals:
0 = 24
Then u get :
8x = 24
Then u divide 8 on each side:
8x = 24
8x divided by 8 equals x
24 divided by 8 is 3:
So u get X = 3..........................................
