-12-x = 2 => ?
2x - 14 = -4 => ?
x : (-9) =4 => ?
-108 :(-x) =6 => ?

Answer 1

[tex]-3x=27\\ =\ \textgreater \ x=27:-3\\ =\ \textgreater \ x=-9\\\\ -12-x=2\\ =\ \textgreater \ -x=-2-12\\ =\ \textgreater \ -x=-10\\ =\ \textgreater \ x=10\\\\ 2x-14=-4\\ =\ \textgreater \ 2x=4-14\\ =\ \textgreater \ 2x=10\\ =\ \textgreater \ x=5\\\\ x:(-9)=4\\ =\ \textgreater \ x=4*(-9)\\ =\ \textgreater \ x=-36\\\\ -108:(-x)=6\\ =\ \textgreater \ (-x)=-108:6\\ =\ \textgreater \ (-x)=-18[/tex]

Answer 2

-3x=27
x=27/-3
x=-9

-12-x=2
-x=2+12
x=-14

2x-14=-4
2x=-4+14
2x=10
x=10/2
x=5

x:(-9)=4
x=4*(-9)
x=-36

(-108):(-x)=6
-x=(-108)/6
-x=-18
x=18
