Verified answer

(2/3x+1/6)*1 1/5=2 3/5
2/3х + 1/6 = 2 3/5 : 1 1/5
2/3х + 1/6 = 13/5 : 6/5
2/3х + 1/6 = 13/5 * 5/6
2/3х + 1/6 = 13/6
2/3х = 13/6 - 1/6
2/3х = 12/6
2/3х = 2
х = 2 : 2/3
х = 2 * 3/2
х = 3

Nurzhan94 $\frac{2}{3x} + \frac{1}{3} = \frac{13}{5} : \frac{6}{5} 

$

$\frac{2}{3x} + \frac{1}{3} = \frac{13}{5} * \frac{5}{6}$

$\frac{2}{3x}+ \frac{1}{3} = \frac{13}{6}$

$\frac{2}{3x} = \frac{13}{6} - \frac{1}{3}$

$\frac{2}{3x} = \frac{13-2}{6}= \frac{11}{6}$

$\frac{2}{3x} = \frac{11}{6} 


3x*11=2*6

33x=12 

$

$x= \frac{12}{33}$

x= $\frac{4}{11}$
