## tiff1998g 2 years ago solve for x 132 = 1 over 2x + 2 (x - 9)

1. sue101

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

2. tiff1998g

$\frac{ 1 }{ 2 }$

3. sue101

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

4. tiff1998g

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

5. tiff1998g

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

6. jiteshmeghwal9

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

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!
