Question

3 x - 9 x + 7 - 3 = -8 solve for x, polpak

Answer 1

-6x=-12
x=2

Answer 2

Start by adding 3 to -8. Then subtract 7 from the left side of the equation and then the right..
sooo....
3x-9x+7=-5
3x-9x=-12
Then factor out a three from the x..
3(x-3x)=-12

Answer 3

Ankur, stop giving people solutions they could just get directly from wolframalpha, etc. They want help, not answers. Nobody cares if you know how to do it.

Answer 4

Then you divide by three to get rid of of the product..
x-3x=-4

Answer 5

@ankur504Yes, Please stop....I find it aggravating...

Answer 8

@ Kandyse, Kinda...

Answer 9

I don't think you need to factor out a 3 so much as you just need to combine your x's

Answer 10

Artist, recall that anything you do to one side of an equation you can also do to the other.

Answer 11

Yeah, then factor out an x, so you have x(1-3)

Answer 12

then you have -2x

Answer 13

@ polpak, yes...That is what i was taught...

Answer 14

then you simply divide -2 to both sides of the equation, because as polpak said, you do it to both sides of the equation :)

Answer 15

Sooo, then you have x=2 :)
