okay the first thing i would do is multiply the first 3 into the parenthesis.
3(2x - 4) - 4 (3x - 2)
6x - 12 - 4 (3x - 2)
now i will multiply the 4 into its parenthesis.
6x - 12 - 4 (3x - 2)
6x - 12 - 12x - 8
now i will rearange the numbers so the X's go together and the numbers without X's go together.
6X - 12x -12 - 8
now i will add all of the X terms, and all of the numbers without X's.
-6 X - 20
done.

distribute
3(2x-4)-4(3x-2) =
(3*2x-3*4)+(-4*3x-4*(-2)) =
now perform the multiplications
(6x-12)+(-12x+8) =
okay to drop parentheses and associate like terms
6x-12x-12+8 =
perform the additions/subtractions
-6x-4
stop now that final answer has been attained

to simplify, first, multiply items inside bracket by number outside:
3(2x-4) =6x-12, and -4(3x-2)=-12x+8, so
6x-12-12x+8-combine x's and numbers, so
-6x-4 is the SIMPLIFIED ANSWER

its so easy dude.
ill expect that youre just a little kid thats why you dont know this. ill laugh at you if youre some college dude. lol. jk.
heres the steps.
distribute the 3 into 2x-4
=6x -12
then distribute the -4 into 3x-2
= -12x+8
you have this..
= 6x-12-12x+8
then combine like terms
= -6x-12x -12+8
= -6x -4
there you go. :)
hope this helps

3(2x-4)- 4(3x-2)
3 times 2x=6x
3 times -4= -12
6x-12 -4 (3x-2)
-4 times 3x= -12x
-4 times -2 = 8
6x -12 - 12x +8
now combine like terms
6x -12x= -6x
-12 +8 = -4
and ur answer is
-6x - 4

3(2x-4)= 6x-12
-4(3x-2)= -12x+8
then add the 2 components above:
6x-12-12x+8 = -6x-4, u can also write this answer as, -1(6x+4)//

3(2x-4) - 4(3x-2)
6x-12-12x-8
-6x -6x
-12-6x-8
+8 +8
=-4-6x
Haha dnt tell ur teacher that i gave u this answer if it is wrong i took algerbra like 6 years ago lol
