Answer:
   x = 6
Step-by-step explanation:
The sum of segments is used:
   EF +FG = EG
   3x +(5x +16) = 11x -2 . . . . substitute given expressions
   8x +18 = 11x . . . . . . . . add 2
   18 = 3x . . . . . . . . subtract 8x
   6 = x . . . . . . divide by 3
The value of the variable is 6.
__
<em>Check</em>
The segment lengths are ...
   EF = 3x = 3·6 = 18
   FG = 5x+16 = 5·6 +16 = 46
   EG = 11x -2 = 11·6 -2 = 64 = 18+46 . . . answer is correct
