math 012

posted by .

Hi, I am trying to do homework for my math 012 class- solving linear equations- and I need help with 9 of the problems. I would really appreciate any help with this. I can do the problems and send them to you, or however you prefer.

Thanks!

    ok thanks!

    -6(1x-3)-26=-8

    -6(1x-3)-26=-8
    -6x+18-26=-8
    -6x+44=-8
    -44 -44
    -6x=36
    -6 =-6
    x=6

    It is conventional to just write x, instead of 1x, wheneve the coefficient of an algebraic variable is 1.

    There is a mistake in what you did.

    Let's take a look.
    -6(x-3)-26 = -8
    -6x +18 -26 = -8
    (You got that far OK)
    -6x - 8 = -8
    -6x = 0
    x = 0

    One more thing with this problem if you can explain for me. how come in the forth step, it is -6x=0?

  • math 012 -

    I added 8 to both sides of the equation, thus eliminating it.

    how to solve this math problem x/3 - 8 = -2
