    Subtract -3 from both sides, then divide both sides by -5/12

    b) 3x + 5 ≥ 6x 7
    Subtract 3x from both sides, then add 7 to both sides, then divide both sides by 3

    c) 3x + √6 = 2x - 3√6
    Subtract 2x from both sides, then subtract \sqrt{6} from both sides

    You post them. That way you prove that you are working.
