Question

Solve, write your answer in interval notation and graph the solution set.

1a. 2 - 5x less than 12

1b. 2(x+5) - 1 less than or equal to x+5

Answer 1

Solve, write your answer in interval notation and graph the solution set.

1a. 2 - 5x less than 12

1b. $2(x + 5) - 1$ less than or equal to $x + 5$

1a. $2 - 5x < 12, 5x > -10, x > -2, x \in (-2; +\infty)$

---

1b. $2(x + 5) - 1 \leq x + 5, 2x + 10 - 1 \leq x + 5, x \leq -4, , x \in (-\infty; -4]$.
