alg2 check?

solve 3(8x-2)=46-2(12x+1)

24x-6=46-24x+2
24x-6=48-24x
48x-6=48
48x=42
x=42/48 or 7/8
what where the two mistakes made in the problem?

I said the 46 going to 48 and subtracting the 6 from 48?

  1. correct solution:

    24x-6=46-24x-2
    48x = 50
    x = 50/48 = 25/24

    the first major error is the +2 instead of -2
    second error is subtracting 6 instead of adding 6 to both sides

    I think you had picked them out correctly

    Did I do this problem the correct way if so is there a shorter way to explain this? x(x + 6)(x + -4) = 24x x(6 + x)(x + -4) = 24x x(6 + x)(-4 + x) = 24x (6 + x) * (-4 + x x(6(-4 + x) + x(-4 + x)) = 24x x((-4 * 6 + x * 6) + x(-4 +

    The fact that there was that nice symmetry to the question, makes it easier than it first appears. I had it as: (a/b + b/a)รท(b/a - a/b) look at (a/b + b/a) the common denominator for this would be ab, so a/b + b/a = (a^2 +

    is this correct... (3x^2+4x-3)^2-(3x^2-x+2)^2 then is it this (9x^4+24x^3-2x^2-24x+9)-(9x^4-6x^3+13x^2-4x+4) or this 9x^4+24x^3-2x^2-24x+9-9x^4-6x^3+13x^2-4x+4 should it have brakets or not that's my only problem thanks
