Answer 1

Пошаговое объяснение:

$14 \frac{1}{2} - x = 9 \frac{5}{6} \\ x = 14 \frac{1}{2} - 9 \frac{5}{6} \\ x = 13 \frac{3}{2} - 9 \frac{5}{6} \\ x = 4 \frac{9 - 5}{6} \\ x = 4 \frac{4}{6} \\ x = 4 \frac{2}{3}$

$(x + 4 \frac{7}{8} ) - 5 \frac{1}{2} = 9 \frac{3}{4} \\ x + 4 \frac{7}{8} = 9 \frac{3}{4} + 5 \frac{1}{2} \\ x + 4 \frac{7}{8} = 15 \frac{1}{4} \\ x = 15 \frac{1}{4} - 4 \frac{7}{8} \\ x = 14 \frac{5}{4} - 4 \frac{7}{8} \\ x = 10 \frac{3}{8}$

Answer 2

Пошаговое объяснение:

14 1/2 - х = 9 5/6

х = 14 1/2 - 9 5/6

х = 14 3/6 - 9 5/6

х = 13 9/6 - 9 5/6

х = 4 4/6

х = 4 2/3

(х + 4 7/8) - 5 1/2 = 9 3/4

х + 4 7/8 = 9 3/4 + 5 1/2

х + 4 7/8 = 9 6/8 + 5 4/8

х + 4 7/8 = 14 10/8

х = 14 10/8 - 4 7/8

х = 10 3/8
