Assume question SHOULD be written as :-
(4 - x) / (x - 2) = - 2 / (x - 2)
4 - x = - 2
x = 6

(4-x)/(x-2)=-2/(x-2)
(4-x)=-2
-x=-4-2
-x=-6
x=6

4-x/x-2 = -2/x-2
4-x = -2
-x=-2-4
x=6

4-x/x-2=-2/x-2

In this equation you can cancel the x-2 because is dividing in both sides

so you get

4-x=-2
solving for X
4+2=x
x=6

(4 - x)/(x - 2) = -2/(x - 2)
4 - x = -2
-x = -2 - 4
-x = -6
x = -6/-1
x = 6
