If 3 x+ (2 x- 7 6 )=-2 , then x is equal to ( where m I)

Options

A3 (6 m-1)
B3 (6 m+1)
C3 (2 m+1)
Dnone of these

Correct answer

B. 3 (6 m+1)

Step-by-step solution

aligned & 1+ 3 x+1- [ ( 2 + (2 x- 7 6 ) ) ]=0 & 2 ^2 3 x 2 +1- (2 x- 2 3 )=0 & 2 ^2 3 x 2 +2 ^2 (x- 3 )=0 aligned 3 x 2 =0, (x- 3 )=0 x = 3 , and x = 3 , 2 3 , 7 3 , x = 3 is the common value which satisfies both x=2 n + 3 =(6 n+1) 3
