Chapter A.9, Problem 58AYU

To determine

To solve: Each inequality. Express your answer using set notation or interval notation. Graph the solution set.

Answer to Problem 58AYU

$\left\{x\right|x > -2\}$ or $(-2,\infty )$

Explanation of Solution

Given:

$2x + 5 > 1$

Calculation:

$2x + 5 > 1$

$2x + 5 - 5 > 1 - 5$   -----(Subtract $5$ on both sides)

$2x > -4$

$\frac{2x}{2} > \frac{-4}{2}$   -----(Divide $2$ on both sides)

$x > -2$

The solution set is $(x|x > -2)$ or using interval notation, all numbers in the interval $(-2,\infty )$
