    -2(x-4)-(8x-3)=2-(6x-1) What did you do first?

    I will do my best -2(x-4)-(8x-3)=2-(-6x-1). I think this is the problem if i understood correctly right? @michaelhale

    a negative (-) times -3 = a positive number, hence +3

    Don't be afraid to rewrite things a bit. It will help you win the battle. -2(x-4)-(8x-3)=2-(6x-1) First parentheses -2x + 8 - (8x-3) = 2 - (6x-1) Next parentheses -2x + 8 - 8x + 3 = 2 - (6x-1) Last parentheses -2x + 8 - 8x + 3 = 2 - 6x + 1 See how easy that is to follow, now that we have written the entire expression every step of the way? Okay, now what?

    so when I see -(8x_3) I distribute the - sign as a coefficient of -1

    That is a reasonable understanding. It is the same on the last parentheses.

    -2x+4-8x+3=2-6x+1 =>-10x+5=-6x+3 =>-4x=-2 =>x=2
