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

    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!
