Пошаговое объяснение:

10 5/8 + (-х - 5 11/12) = -6 1/2

-х - 5 11/12 = -6 1/2 - 10 5/8

-х - 5 22/24 = -6 12/24 - 10 15/24

-х - 5 22/24 = -16 27/24

-х = -16 27/24 + 5 22/24

-х = -11 5/24

х = 11 5/24

[tex]10 \frac{5}{8} + ( - x - 5 \frac{11}{12} ) = - 6 \frac{1}{2} \\ - x - 5 \frac{11}{12} = - 6 \frac{1}{2} - 10 \frac{5}{8} \\ - x - 5 \frac{11}{12} = - 6 \frac{4}{8} - 10 \frac{5}{8} \\ - x - 5 \frac{11}{12} = - 16 \frac{9}{8} \\ - x - 5 \frac{11}{12} = - 17 \frac{1}{8} \\ x + 5 \frac{11}{12} = 17 \frac{1}{8} \\ x = 17 \frac{1}{8} - 5 \frac{11}{12} \\ x = 17 \frac{3}{24} - 5 \frac{22}{24} \\ x = 16 \frac{27}{24} - 5 \frac{22}{24} \\ x = 11 \frac{5}{24} [/tex]
