3x+24=12x
adding -3x
24=9x
dividing y 9
x=24/9
=8/3
=2 2/3

3/2 (x+8) = 6x
         x+8 = ⅔ × 6x
         x+8 = 4x
      4x - x = 8
           3x = 8
             x = 8/3
                = 2⅔

i may've read ur equation in the wrong way, here if the equation is something else like this

      3
————— = 6x
2 ( x + 8 )

              3 = 6x { 2 ( x + 8 ) }
              3 = 6x ( 2x + 16 )
              3 = 12x² + 96x
              0 = 12x² + 96x - 3
              0 = 4x² + 32x - 1
              0 = x² + 8x - ¼
              0 = x² + 8x + 16 - 16 - ¼
     16 + ¼ = x² + 8x + 16
         65/4 = ( x + 4 )²
                        ____
        x + 4 = ±√65/4
                            ____
              x = -4 ± √65/4
hence,
x = 0.03113 or x = -8.03113

3/2 (x+8) = 6x simplify
3X+24/2=6x multiply each side by 2
3X+24=12X move x values to one side
24=9X divide each side by 9
x=24/9 reduce the fraction
x=8/3
x=2 2/3

3/2(x + 8) = 6x

2[3/2 (x + 8)} = 2(6x)

3(x + 8) = 12x

3x + 24 = 12 x

3x + 24 - 3x = 12x - 3x

24 = 9x


24/9 = 9x/9

24/9 = x

8/3 = x

2 2/3 = x

1. distribute
3x/2 + 12 = 6x

2. multiply everything by 2 to get rid of the fraction
3x + 24 = 12x

3. subtract 3x from both sides
24 = 9x

4. divide both sides by 9
24/9 = x

5. reduce by dividing by a common factor (3)

x = 8/3

3/2(x +8) =6x
3(x+8) = 2(6x) =12x Multipy across the board by 2
3x +24 = 12x
24 = 12x -3x
24 =9x
24/9 =x

Therefore x=2.666666

It almost certainly means that you should do your own homework.

Is this 3 over 2(x+8) or 3/2 times (x+8)?

2007-01-05 02:42:06 · answer #7 · answered by Chris H 3 · 1 0

3/2(x+8) = 6x
Take the 2 frm the denominator to the RHS
3(x+8)= 2*6x
3x+24=12x
24=12x-3x
24=9x
24/9=x

therefore when simplified x=8/3

hope that helps!

(hmm it cud be how xyeslam has shown it above...the 2nd method i mean)

Please re-check the problem to make sure you typed it correct > is it (3/2)(x+8) = 6x Or [3/2(x+8)] = 6x?

3/2(x+8)=6x
x+8=6x(2/3)
X+8=4x
3x=8
x=8/3
