Question

реши уровненение 19/30-(х+9/30)=7/30​

Answer 1

19/30 - ( X + 9/30 ) = 7/30

19/30 - X - 9/30 = 7/30

10/30 - X = 7/30

X = 3/30 = 1/10

Answer 2

Ответ:

$0,1$

Пошаговое объяснение:

$\dfrac{19}{30}- \bigg (x+\dfrac{9}{30} \bigg )=\dfrac{7}{30};$

$x+\dfrac{9}{30}=\dfrac{19}{30}-\dfrac{7}{30};$

$x+\dfrac{9}{30}=\dfrac{19-7}{30};$

$x+\dfrac{9}{30}=\dfrac{12}{30};$

$x=\dfrac{12}{30}-\dfrac{9}{30};$

$x=\dfrac{12-9}{30};$

$x=\dfrac{3}{30};$

$x=\dfrac{1}{10};$

$x=0,1;$
