6(4x - 3)
do distribution
24x -18
and there is your answer
OpenStudy (anonymous):
How did you get 24x??
OpenStudy (anonymous):
4 + 2 = what?
OpenStudy (anonymous):
You have to distribute 4 first..

not that I remember of..
OpenStudy (misty1212):
your answer is almost right
OpenStudy (misty1212):
but \(2-12=-10\) not \(-14\)
OpenStudy (anonymous):
16x - 18 + 2
16x - 16
OpenStudy (misty1212):
\[2+4(x-3)\\2+4x-12\\
2x-10\]

yes, what Misty said.
OpenStudy (anonymous):
sorry did my math wrong :/
OpenStudy (anonymous):
misty is correct
OpenStudy (anonymous):
c:
OpenStudy (anonymous):
2+16x-12
-2 -2

You don't subtract, because the 2 isn't over an = sign.
OpenStudy (anonymous):
You only change the sign if it's on the opposite side of an = sign.
Such as:
4x -2 = 6
+2 +2
4x = 8
Divide by 4
x=2
OpenStudy (anonymous):
so yes, misty is right.
OpenStudy (anonymous):
Hope this helps. ^-^
OpenStudy (anonymous):
She means 4x -10 though, i think.

I think @misty1212 had the equation wrong she had it at 2+4(x−3)
2+4x−12
2x−10
OpenStudy (anonymous):
Oh yes, you're right. Hold on.
OpenStudy (anonymous):
So 16x -10..
OpenStudy (anonymous):
@xFrenchFryx isn't -12-2 = -14? so 16x-14?
OpenStudy (anonymous):
Where is the -2 though?

It's just a 2.
OpenStudy (anonymous):
So it's -12 + 2
OpenStudy (anonymous):
why + 2?
here is my solution
2+16x-12
-2 -2
-----------
16x-14 @xFrenchFryx
OpenStudy (anonymous):
I do have to go though, so I hope you get the answer. ;3
OpenStudy (anonymous):
I explained that you don't change the 2 to a negative unless it's on the opposite side of an = sign.
