Answer 2

Пошаговое объяснение:

$17 \frac{1}{4} - x = 7 \frac{11}{12} \\ 3(17 \times 4 + 1) - 12x = 7 \times 12 + 11 \\ 3(68 + 1) - 12x = 7 \times 12 + 11 \\ 3 \times 69 - 12x = 7 \times 12 + 11 \\ 207 - 12x = 7 \times 12 + 11 \\207 - 12x = 84 + 11 \\ 207 - 12x = 95 \\ - 12x = 95 - 207 \\ - 12x = - 112 \\ x = - 112 \div ( - 12) \\ x = \frac{28}{3} = 9 \frac{1}{3}$
