    2x + 7 ≤ 3x - 5

    Isolate the x. Subtract 3x and 7 from both sides

    2x (-3x) + 7 (-7) ≤ 3x (-3x) - 5 (-7)

    2x - 3x ≤ - 5 - 7

    Combine like terms

    (2x - 3x) ≤ (-5 - 7)

    -x ≤ - 12

    Isolate the x. Divide - 1 from both sides. Remember that when dividing by a negative number, you must flip the sign.

    (-x) / -1 ≤ (-12) / -1

    x ≥ - 12/-1

    x ≥ 12

    x ≥ 12 is your answer

    2x + 7 < = 3x - 5

    Treat < = as an = sign unless you divide or multiply by a negative number.

    2x + 12 < = 3x

    x < = 12

    The answer is all real numbers less than or equal to 12.
