Polynomials

I am stuck with this question and need some help.
7x-2(x-3)=9x-5
I have no idea really what to do on this question.  I tried multiplying 7x-2 into x-3 and then trying to find out what is x, but that doesn't work.  Can anyone help?

Re: Polynomials

you do not use 7x-2 just use -2 than solve for x and you should get x=4/11

Re: Polynomials

7x - 2(x - 3) = 9x - 5
7x - 2x + 6 = 9x - 5
5x + 6 = 9x - 5
11 = 4x
