Question

Which number line represents the solution set for the inequality –4(x + 3) ≤ –2 – 2x?

Answer 1

For this case we have the following inequality:

$-4 (x + 3) \leq-2-2x$

Applying distributive property on the left side we have:

$-4x-12 \leq-2-2x$

Adding 2x to both sides of the inequality we have:

$-4x + 2x-12 \leq-2\\-2x-12 \leq-2$

Adding 12 to both sides of the inequality we have:

$-2x \leq-2 + 12\\-2x \leq10$

Dividing by 2 to both sides of the inequality:

$-x \leq \frac {10} {2}\\-x \leq5$

Multiplying by -1 on both sides, taking into account that the sense of inequality changes:

$x \geq-5$

Thus, the solutions are given by all values ​​greater than or equal to -5.
