Question

помогите решить уравнения.

Answer 1

$\frac{18}{30} - x = \frac{4}{30} + \frac{6}{30} \\ \\ \frac{4}{30} + \frac{6}{30} = \frac{10}{30} \\ \\ x = \frac{10}{30} - \frac{4}{30} = \frac{6}{30} = \frac{1}{5}$

Answer 2

Ответ:

5.

$\frac{64}{70} - (x + \frac{26}{70} ) = \frac{5}{70}$

$\frac{64}{70} - x - \frac{26}{70} = \frac{5}{70}$

$\frac{38}{70 } - x = \frac{5}{70}$

$- x = \frac{5}{70} - \frac{38}{70}$

$x = \frac{32}{70}$

6.

$x + \frac{27}{46} = \frac{35}{46} + \frac{2}{46}$

$x + \frac{27}{46 } = \frac{37}{46}$

$x = \frac{37}{46} - \frac{27}{46}$

$x = \frac{10}{46}$
