: I am having problems on equations like 1/2 x -1= -1
I guess you just typed any old equation; that's a BAD example...
You probably mean: 1/2 (x - 1) = -1
That's read: one half times (x less one) = minus one
(x - 1) / 2 = -1 is the same thing; ok? if not, bye bye
so x - 1 = -2; x = -1
Now, if you put -1 instead of x in the equation,
you'll get 1/2 times -2 which does equal -1; ok?
