3X - 36 ?????
Or,
3X - 3 = 6 ?????
I will do both. First, 3X - 36
3X - 36
factor out the 3
3(X - 12)
and by the zero property rule
X = 12
=====
Now, 3X - 3 = 6
3X - 3 = 6
add 3 to each side
3X - 3 + 3 = 6 + 3
3X = 9
divide each sides integer by 3
(3/3)X = 9/3
X = 3
=======
I leave the checking to you.

(x - 3x - 6) / 6 = (3x + 2) / 2 ∴2(3x + 2) = 6(3x + 2) ∴6x + 4 = 18x = 12 ∴12x = -8 ∴x = -2/3
6x + 6 = 3x - 2 Bring 3x to the left and subtract: 6x - 3x = 3x 3x + 6 = -2 -2 - 6 = -8 -8 / 3 X = -8/3
If you mean: 2x-3 = 3x+3 then x = -6
6
3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
