Question

х : (-1,5)= - 9; пж добомога
в) (х+6) : (– 1) = 25;
г) (х – 4) : 6 + 39 = – 13

Answer 1

Ответ:

х : (-1,5)= - 9;

x : (-3:2)= - 9;

- x * 2:3= - 9;

-2:3x= - 9;

x= 27:2;

x=13 1:2

(х+6) : (– 1) = 25;

-(x+6)=25;

-x=25+6;

-x=31;

x=-31;

(х – 4) : 6 + 39 = – 13;

x-4:6+39=-13;

x+230=-78;

x=-78-230;

x=-380;
