[tex]2 \times (x + \frac{1}{5} ) = 1 \frac{3}{4} \\ 2 \times (x + \frac{1}{5} ) = \frac{4 \times 1 + 3}{4} \\ 2 \times (x + \frac{1}{5} ) = \frac{7}{4} \\ x + \frac{1}{5} = \frac{7}{4} \div 2 \\ x + \frac{1}{5} = \frac{7}{4} \times \frac{1}{2 } \\ x + \frac{1}{5} = \frac{7}{8} \\ x = \frac{7}{8} - \frac{1}{5} = \frac{35}{40} - \frac{8}{40} = \frac{27}{40} [/tex]
