``4x - (2x + 1) = 3 - $\frac{1}{3}$ + x``
``⇒ 4x - 2x - 1 = 3 - $\frac{1}{3}$ + x``
``⇒ 2.2x - 2x - 1 = 3 - $\frac{1}{3}$ + x``
``⇒ 2x (2 - 1) - 1= 3 - $\frac{1}{3}$ + x``
``⇒ 2x - 1 = 3 - $\frac{1}{3}$ + x``
``⇒ 2x - 1 = $\frac{9}{3}$ - $\frac{1}{3}$ + x``
``⇒ 2x - 1 = $\frac{8}{3}$ + x``
``⇒ 2x - 1 + 1 = x + $\frac{8}{3}$ + 1``
``⇒ 2x = x + $\frac{11}{3}$``
``⇒ 2x - x = x + $\frac{11}{3}$ - x``
``⇒ x = x + $\frac{11}{3}$ - x``
``⇒ x = $\frac{11}{3}$``
`` Vậy x = $\frac{11}{3}$``
