Solving Compound Linear Inequalities

Example

Solve: Then, graph the solution on a number line.

Solution	x <		≤ x + 3
To clear the fractions, multiply each part by the LCD, 5.	5 Â· [x] <		≤ 5 Â· [x + 3]
Distribute. Subtract 4 from each part. Simplify. Subtract 5x from each part. Simplify.	5x < 5x - 4 < 5x - 4 < 5x - 4 - 5x < -4 <	7x + 4 7x + 4 - 4 7x 7x - 5x 2x	≤ 5x + 15 ≤ 5x + 15 - 4 ≤ 5x + 11 ≤ 5x + 11 - 5x ≤ 11
Divide each part by 2.	<		≤
Simplify.	-2 <	x	≤

To graph the solution, place an open circle at -2 and a closed circle at .

Then, shade the region between the plotted points.
