a) $\frac{3x+2}{2}$ - $\frac{3x+1}{6}$ = $\frac{5}{3}$ + 2x
<=> $\frac{3(3x+2)}{2.3}$ - $\frac{3x+1}{6}$ = $\frac{5.2}{3.2}$ + $\frac{6.2x}{6}$
<=> 9x + 6 - 3x - 1 = 10 + 12x
<=> 9x - 3x - 12x= 10 + 1 - 6
<=> -6x = 5
<=> x = $\frac{-5}{6}$
Vậy x = $\frac{-5}{6}$
Cho mk ctlhn và vote 5 sao cho mk nha!!!!
