Question

помогите пожалуйста математика 3 уравнения
$5 - 7x + 4x = 4 \frac{4}{7 } \\ 3(x - \frac{4}{19}) = 2 \\ 4x - \frac{4}{9} = \frac{5}{6} + 2x$
​

Answer 1

Ответ:

Объяснение:

1) 5 - 7x + 4x = 4 4/7

5 - 3x = 4 4/7

3x = 3/7

x = 7

2) 3(x - 4/19) = 2

3x - 12/19 = 2

3x = 2 12/19

x = 1,14

3) 4x - 4/9 = 5/6 + 2x

4x - 2x = 5/6 + 4/9

2x = 1 5/18

x = 1 13/23
