Question

-12 ( -4x + 6 ) -x + 7 - (-9x)

Show your work please.

Answer 1

how about i guide you through, sound good? :]

Answer 2

Yep sounds good to me.

Answer 3

ok so
the distributive property with -12(-4x +6x)
you get 48 -72

Answer 4

-x +7 +9x because -1( -9x ) turns that 9 into a positive
so 48 - 72 - x + 7 + 9x combine the like terms you get?

Answer 5

-12 (-4x + 6) = -12 . -4x + -12 . 6 = 48x -72
- (-9x) = 9x

48x - x + 9x - 72 = 56x - 72 = 7x - 9

Answer 6

is it right?

Answer 7

idk where your getting all these equal signs from?
i got 48 - 72 - x + 7 + 9x
-17 +8x but you never had that equal to anything

Answer 8

eh.., i'm forget.., it should be 48x - x + 9x - 72 + 7 = 56x - 65

about i get 48x is because -12 times -4x is 48x

Answer 9

Woah, so confused guys.

Answer 10

48x - 72 -x + 7 + 9 = 0
combine the like terms

Answer 11

so, we would use the " eye brow method here. -12 x -4 = ? and -12 x 6 = ? correct?

Answer 12

so it would be, 48x - 72 -1x + 7 + 9 = 0 ?
Then from there we would add the varibles or seperate terms?

Answer 13

combining like terms, yes

Answer 14

like... 48x - 1x = 47x
-72 + 7 + 9 = 56 ?

Answer 15

- 56 **

Answer 16

so it would end up being....

47x - 56 ?

Answer 17

yeah and i'm guessing you need to solve for x?

Answer 18

No, um. Simplify I guess you could call it. Its just add em up. write it. We havent got that far yet. Thanks though. I have a better understanding now :D

Answer 19

i want know how you get 9.., i think -(-9x) is - times -9x = 9x ( - x - = + ), and where is the "x" variable?? O.O

Answer 20

All varibles without a stated number are always 1.
