[tex]( \frac{2}{3} x + \frac{1}{6} ) \times 1 \frac{1}{5} = 2.6 \\ \frac{2}{3} x + \frac{1}{6} = 2 \frac{3}{5} \div 1 \frac{1}{5} \\ \frac{2}{3} x + \frac{1}{6} = \frac{13 \times 5}{5 \times 6} \\ \frac{2}{3} x + \frac{1}{6} = \frac{13}{6} \\ \frac{2}{3} x = \frac{13}{6} - \frac{1}{6} \\ \frac{2}{3} x = \frac{12}{6} \\ \frac{2}{3} x = 2 \\ x = 2 \div \frac{2}{3} = \frac{2 \times 3}{2} \\ x = 3[/tex]
