Answer 2

$(x- 3\frac{2}{5} )+ 7 \frac{4}{5} = 9 \frac{1}{5} \\ \\ x-3 \frac{2}{5} = 9 \frac{1}{5} - 7 \frac{4}{5} \\ \\ x - 3\frac{2}{5} = \frac{46}{5} - \frac{39}{5} \\ \\ x - 3\frac{2}{5} = \frac{7}{5} \\ \\ x- \frac{17}{5} = \frac{7}{5} \\ \\ x = \frac{7}{5} + \frac{17}{5} \\ \\ x = \frac{24}{5} \\ \\ x = 4,8 \\ \\ \\ OTBET: 4,8$
или $4 \frac{4}{5}$
