    We are given : - 3 (4-6x) < x+5.

    Solution: - 3 is in front of Parenthesis.

    We need to multiply - 3 by (4-6x).

    So, we need to applying distributive property.

    On distributing, we get

    -12+18x < x+5 (By distributive property)

    The reverse operation of addition is subtraction. So we need to subtract x from both sides, we get

    -12+18x-x < x-x+5 (By subtraction property of equality).

    -12+17x < 5

    Now, we need to get rid - 12 from left side.

    So, we need to apply addition property of equality, we need to add 12 on both sides, we get

    -12+12+18x < x+5+12 (By addition property of equality)

    17x < 17

    We need to get rid 17 from left side. So we need to apply division property of equality.

    On dividing both sides by 17, we get

    17x/17 < 17/17 (By division property of equality)

    x < 1.
