Question

0,3-(7,2+х)=-1,5.

-2 1/3+(х-1/6)=-4 5/9.

Answer 1

Ответ:

Пошаговое объяснение:

0,3-(7,2+х)=-1,5.

-(7,2+x) = -1.5-0.3;

7.2+x = 1.8;

x=1.8-7.2;

x= -5.4.

------------------------------------

-2 1/3+(х-1/6)=-4 5/9.

x-1/6 = -4 5/9 + 2 1/3; => НОК(6;3) = 9 => -4 5/9 + 2 3/9 = -(4 5/9 - 2 3/9) =

= -2 2/9;

x-1/6 =  -2 2/9;

x= -2 2/9+1/6; => НОК(9;6) = 18 => -2 4/18 + 3/18 = -(2 4/18-3/18) = -2 1/18.

x= -2 1/18.
