If (10x + 2)/4 - (3x - 6)/18 = (2x + 4)/3,
Then what is the value of x?
Choose the correct choice from the following answers:
A) 3
B) - 3
C) 10 / 3
D) 3 / 10
E) - 10 / 3

Rationale: ( 10 x + 2 ) / 4 - ( 3 x - 6 ) / 18 = ( 2 x + 4 ) / 3 = > 18 ( 10 x + 2 ) / 4 - ( 3 x - 6 ) = 18 ( 2 x + 4 ) / 3 = > 4.5 ( 10 x + 2 ) - 3 x + 6 = 6 ( 2 x + 4 ) = > 45 x + 9 - 3 x + 6 = 12 x + 24 = > 45 x - 3 x - 12 x = 24 - 9 - 6 = > 30 x = 9 = > x = 9 / 30 = > x = 3 / 10 answer : d
Answer: D
