4 6. Теңдеуді шеш: A) |12x-51-5 b) 14x-31=-11 Точлеулi купу аркылы шыгарыныз (4)​

Answer 1

Ответ:

$|12x - 51| = 5 \\ 12x - 51 = 5 \\ 12x = 51 + 5 \\ 12x = 56 \\ x = 56 \div 12 \\ x = 4 \frac{8}{12} = 4 \frac{2}{3}$

и

$12x - 51 = - 5 \\ 12x = - 5 + 51 \\ 12x = 46 \\ x = 46 \div 12 \\x = 3 \frac{10}{12} = 3 \frac{5}{6}$

2.

$14x - 31 = - 11 \\ 14x = - 11 + 31 \\ 14x = 20 \\ x = 1 \frac{6}{14} = 1 \frac{3}{7}$
