No, it's not 3. It's (-9)...
3x -12 -6x+2=17
-3x= 17 +12 -2
-3x= 27
x= 27/-3
x=-9

1) 3X - 12 - 6X + 2 = 17
2) -27 = 3X
3) X = -9
Can you follow what I did from step 1 to step 2?
1) I added 6X to the other side of the equation and then subtracted 3X giving me 3X on the right side. Then I combined -12 and + 2 on the left side which equals -10. Then I subtracted 17 from -10 giving me -27.

3(x - 4) - 2(3x - 1) = 17
3x - 12 - 6x + 2 = 17
- 3x = 27
x = - 9

3 (x-4) - 2(3x-1)=17
3x -12 -6x +2 -17=0
-3x -27 = 0
3x = 27
x=9

work out the parenthesis:
--> 3(x-4)= 3x-12
--> -2(3x-1)= -6x+2
combine like terms:
--> 3x-6x= -3x
--> -12+2= -10
add +10 to both sides:
--> -10+10 cancel out
--> 17+10=27
divide -3 to both sides, leavin 'x' by itself:
--> -3/-3 cancel out
--> 27/-3= -9
x= -9 (is the answer)
