    Answer:

    Inequality Form:  x < −1

    Interval Notation:  (−∞, −1)

    Step-by-step explanation:

    3 (x + 3) −2 < 4

    Simplify 3 (x + 3) − 2.

    Apply the distributive property.

        3x + 3 ⋅ 3 − 2 < 4

    Multiply 3 by 3.

        3x + 9 − 2 < 4

    Subtract 2 from 9.

        3x + 7 < 4

    Move all terms not containing x to the right side of the inequality.

    Subtract 7 from both sides of the inequality.

        3x  < 4 − 7

    Subtract 7 from 4.

        3x  < −3

    Divide each term by 3 and simplify.

        x < −1

    The result can be shown in multiple forms.

    Inequality Form:  x < −1

    Answer:3 + ? = 7, 3 + n = 7, 3 + x = 1

    Step-by-step explanation:

    and so on, where the symbols ?, n, and x represent the number we want to find. We call such shorthand versions of stated problems equations, or symbolic sentences. Equations such as x + 3 = 7 are first-degree equations, since the variable has an exponent of 1. The terms to the left of an equals sign make up the left-hand member of the equation; those to the right make up the right-hand member. Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7.
