Selesaikan persamaan berikut 1/3x + 4 = 4x-1 /5

[tex] \frac{1}{3x} \: + 4 = 4x - \frac{1}{5} \\ \frac{1}{3x} \: - 4x = - \frac{1}{5} \: - 4 \\ \frac{1}{3x} - \frac{12}{3x} \: = - \frac{1}{5} - \frac{20}{5} \\ - \frac{11}{3x} \: = \frac{ - 21}{5} \\ 3.6x = 4.2 \\ x = \frac{4.2}{3.6} \\ x = 1.16[/tex]
