$132 =\frac{ 1 }{ 2x + 2(x-9) }$

2. tiff1998g Group Title

$\frac{ 1 }{ 2 }$

so how is the equation supposed to look like please clarify :)

4. tiff1998g Group Title

its 132 = 1/2x + 2 (x - 9 )

5. tiff1998g Group Title

132 = |dw:1349453073706:dw| x +2 ( x - 9 )

Use parentheses when writing your equation. Otherwise there could be a number of different interpretations.$132 = \frac{1}{2}x + 2(x-9)$ could be written 132=(1/2)x+2(x-9) Or is it $132 = \frac{1}{2x} + 2(x-9)$?

ah ok now I understand better. So first distribute 2 to x - 9 2x - 18 132 = 1/2x + 2x - 18 Then combine like terms which is 1/2x + 2x 132 = 2 1/2x - 18. Then add 18 to both sides. +18 +18 --------------------- 150 = 2 1/2x Then you divide. I got 60! Hope this helped!
