Question

помогите пж
5 - x = 4/9​

Answer 1

Пошаговое объяснение:

$5 - x = \frac{4}{9} \\ - x = \frac{4}{9} - 5 \\ - x = \frac{4}{9} - \frac{45}{9} \\ - x = \frac{4 - 15}{9} \\ - x = - \frac{41}{9} \\ x = \frac{41}{9} = 4 \frac{5}{9}$

Answer 2

$5 - x = \frac{4}{9}$

$- x + 5 = \frac{4}{9}$

$(5 - 5) - x = \frac{4}{9} - 5$

$- x = \frac{4}{9} - 5$

$- x = ( \frac{4}{9} - \frac{5 \times 9}{9} )$

$- x = \frac{4}{9} + \frac{ - 45}{9}$

$- x = ( \frac{4 - 45}{9} )$

$- x = \frac{ - 41}{9}$

$\frac{ - x}{ - 1} = \frac{ - ( - 41)}{9}$

$x = \frac{ - ( - 41)}{9}$

$x = \frac{41}{9}$
