[tex]-x + \frac{1}{2}x =  \frac{67}{12} + x +  \frac{5}{3} -2[/tex]

looks at all the denominators

2, 12 and 3,  What is the LCM (least common multiple)?  12

times the whole hing by 12.  

12( [tex]-x + \frac{1}{2}x =  \frac{67}{12} + x +  \frac{5}{3} -2[/tex])

-12x  + 6x = 67 + 12x  + 20 - 24  now combine like terms

-6x = 63 + 12x

-12x          -12x  subtract 12x from both sides

-18x  = 63

/-18       /-18

x = -3.5
