Question

(7 1/8-х)+2 3/8=5 7/8

Answer 1

$(7 \frac{1}{8} - x) + 2 \frac{ \\ 3}{8} = 5 \frac{7}{8} \\ ( \frac{57}{8} - x) + \frac{19}{8} = \frac{47}{8} \\ \frac{57}{8} - x + \frac{19}{8} = \frac{47}{8} \\ \frac{19}{2} - x = \frac{47}{8} \\ - x = - \frac{29}{8} \\ x = \frac{29}{8} \: \: 3\frac{5}{8}$
