3. Реши уравнение: X = 17; 21 x + 24 = 8; 37 384 = 24; y 153 = 17. y-14

Решим уравнения:

1. $$ \frac{x}{21} = 17 $$
   $$ x = 17 \cdot 21 $$
   $$ x = 357 $$
2. $$ \frac{x + 24}{37} = 8 $$
   $$ x + 24 = 8 \cdot 37 $$
   $$ x + 24 = 296 $$
   $$ x = 296 - 24 $$
   $$ x = 272 $$
3. $$ \frac{384}{y} = 24 $$
   $$ y = \frac{384}{24} $$
   $$ y = 16 $$
4. $$ \frac{153}{y - 14} = 17 $$
   $$ y - 14 = \frac{153}{17} $$
   $$ y - 14 = 9 $$
   $$ y = 9 + 14 $$
   $$ y = 23 $$

Ответ: 1) 357; 2) 272; 3) 16; 4) 23.
