(1 7/8 x-2 1/3)∙24=4

$(1 \frac{7}{8} x - 2 \frac{1}{3} ) \times 24 = 4 \\ 1 \frac{7}{8} x - 2 \frac{1}{3} = 4 \div 24 \\ 1 \frac{7}{8} x - 2 \frac{1}{3 } = \frac{4}{24} \\ \frac{15}{8} x - \frac{7}{3} = \frac{1}{6} \\ \frac{15}{8} x = \frac{1}{6} + \frac{7}{3} \\ \frac{15}{8} x = \frac{1 + 14}{6} \\ \frac{15}{8} x = \frac{15}{6} \\ x = \frac{15}{6} \div \frac{15}{8} \\ x = \frac{15 \times 8}{6 \times 15} \\ x = \frac{8}{6} \\ x = \frac{4}{3} \\ x = 1 \frac{1}{3}$
