-4×<14

Answer 2

To solve the inequality, let's simplify the expression on the right side of the inequality sign:

2(2x + 3) - 4

First, distribute the 2 to both terms inside the parentheses:

4x + 6 - 4

Simplifying further:

4x + 2

Now, we can rewrite the original inequality:

-12 < 4x + 2

To isolate the variable, we need to move the constant term to the other side of the inequality. Subtract 2 from both sides:

-12 - 2 < 4x

-14 < 4x

Now, divide both sides of the inequality by 4. Remember that when dividing by a negative number, the direction of the inequality sign flips:

-14/4 > x

Simplifying:

-7/2 > x

So the solution to the inequality is x is less than -7/2 or, in interval notation, x ∈ (-∞, -7/2).
