-x + (1)/(2)x =  (67)/(12) + x +  (5)/(3) -2

looks at all the denominators

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

times the whole hing by 12.

12(
-x + (1)/(2)x =  (67)/(12) + x +  (5)/(3) -2)

-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
