12x-6=11x
12x-6+6=11x+6 [adding 6 to both sides]
12x=11x+6
12x-11x=11x+6-11x [subtracting 11x from both sides]
x=6
Check
12x-6
=12*6-6
=72-6=66
11x=11*6=66
Both sides equal.So the answer is OK

12x - 6 = 11x
12x - 11x - 6 = 11x - 11
x - 6 = 0
x = 6
12(6) - 6 = 11(6)
72 - 6 = 66
66 = 66

12x - 6 = 11x
12x - 11x - 6 = 11x - 11
x - 6 = 0
x = 6
check:
12(6) - 6 = 11(6)
72 - 6 = 66
66 = 66

Well I guessed and I got 6 as x. It all works out see? 12x6=72-6=66 and 11x6=66. So they equal the same thing. I am not really begging for the best answer. But I think you will be quite impressed.
