    For this you need to isolate your variable (c)

    So first, you would subtract 4 from both sides.

    So you would have 9c = -27

    Then divide both sides by 9.

    A positive number divided by a negative number is a negative number.

    Solve 3x - x + 2 = 12

    Combine like terms first, so 3x - 1x is 2x, solve from there, 2x + 2 = 12. subtract 2 from both sides, you have 2x = 10.

    You want base value of x, so divide both sides by 2.

    No, you wouldn't add 4 to the +1, you'd multiply, and 4 x 1 is 4.

    No, you don't add them up, this is probably the part that confuses you.

    So, we need to do the opposite of each other term.

    4x + 4 + 8 = 24, we need to get rid of the 8, so we can Subtract 8 from both sides.

    I don't think so, if you added it would make the 12 go up. we want it to go down to 0.
