alg2 check?

posted by .

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?

    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
