Question

уровнение 1946:(014-5х)=14

Answer 1

1946 / (0,14 - 5х) = 14

1946 = 14 * (0,14 - 5х)  ;    1946 = 1,96 - 70х  ;   70х = 1,96 - 1946  ; 70х = - 1944,04

х = - 1944,04 / 70  ;   х =  - 27,772

Answer 2

$1946 \div ( \frac{7}{50} - 5x) = 14 \\ \\ 1946 \div \frac{7 - 250x}{50} = 14 \\ \\ 1946 \times \frac{50}{7 - 250x} = 14 \\ \\ \frac{97300}{7 - 250x} = 14 \\ \\ 97300 = 14(7 - 250x) \\ \\ 6950 = 7 - 250x \\ \\ 250x = 7 - 6950 \\ \\ 250x = - 6943 \\ \\ x = - 27.772$
