No real solutions.
One extraneous solution:
Explanation:
Multiply both sides by
#x-(3(x-3))/2 = 3#
#x - 3/2x + 9/2 = 3#
#-1/2x = -3/2#
#x = 3#
Now to check if
#3/(3-3) - 3/2 stackrel(?)(=) 3/(3-3)#
#3/0 - 3/2 stackrel(?)(=) 3/0#
Hmm... we can't divide by 0, so this solution doesn't work. Therefore,
