Question

. .... помогите пжж пожалуйстааа​

Answer 1

Ответ:

$\frac{2}{3 - x} = \frac{4}{11} \\ 4 \times (3 - x) = 2 \times 11 \\ 12 - 4x = 22 \\ - 4x = 22 - 12 \\ - 4x = 10 \\ x = 10 \div ( - 4) \\ x = - 2 \frac{2}{4} \\x = - 2 \frac{1}{2}$

$\frac{13}{0.5} = \frac{12x - 10}{16} \\ 0.5 \times (12x - 10) = 13 \times 16 \\ 6x - 5 = 208 \\ 6x = 208 + 5 \\ 6x = 213 \\ x = 213 \div 6 \\ x = 35 \frac{3}{6} \\ x = 35 \frac{1}{2}$
