Question

2,1(1-2х)=4,1(3х+2)

Answer 1

Ответ:

$2.1(1 - 2x) = 4.1(3x + 2) \\ 2.1 - 4.2x = 12.3x + 8.2 \\ - 12.3 x - 4.2x = 8.2 - 2.1 \\ - 16.5x = 6.1 \\ x = - \frac{6.1}{16.5}$

Answer 2

Ответ:

$2.1(1 - 2x) = 4.1(3x + 2) \\ 2.1 - 4.2x = 12.3x + 8.2 \\ - 4.2x - 12.3x = 8.2 - 2.1 \\ - 16.5x = 6.1 \\ x =6 \frac{1}{10} \div ( - 16 \frac{5}{10} ) \\ x = - \frac{61 \times 10}{10 \times 165 } \\ x = - \frac{61}{165}$
