X:(-9)=1 ;x:(-11)=-2;-200:x=-40;x:(+14)=-1;-24:x=-8;(-840):(-21)=x;x:37=0;81:x=-9;7490:(-7)=x.ajutor

Answer 1

X:(-9)=1 -->X = 1x(-9 )--> X = -9

X:(-11)=-2 --> X = -2x(-11 )--> X = 22

-200:X=-40--> x = 5-24-x=8-->x=3(-840):(-21)= 40

X:(+14)=-1 --> X = -1 x (-14) --> X = -14

-24:x=-8 --> X = -24/8 --> X = -3

(-840):(-21)=X --> X = - 40

X:37=0 --> X = 0x37 --> X = O

81:X=-9 --> X = -81/9 --> X = -9

7490:(-7)=X --> X = - 1070
