    this is what i got
    [-2x+2]-3=-3
    [-2x+2]=-3+3
    [-2x+2]=0
    since [-2x+2] is 0 that implies x=0 or -2x+2=0
    give me hints if it's not correct

    .14 cents per ounce x 16 ounces= $2.24

    Cost for 16 ounces = $2.24

    5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
    -15x-10-x+3=-16x-20+13
    -15x-x+16x=-20+7+13
    -16x+16x=-20+20
    0x=0 which is undefined there is no solution for this

    The answer is correct :) But,
    There is a mistake because you got 20 and it should be 7. One the left side when you took -10+3 this give you -7 then when you move it over to the right side it will become 7 and then looking at the right side when you took -20+13 that will give you -7 so -7+7=0

    it should be written

    -16x+16x=-7+7
    0=0

    or

    -16x-7=-16x-7
    0=0

    Ok your turn! :biggrin:
