Example: Solving and Graphing
To solve the multi-step linear inequality , start by distributing to simplify the left side, which generates and combines smoothly to . Subtract from both sides to responsibly collect the variables on the left, leading directly to . By subtracting from both sides, the constants are gathered firmly on the right, resulting in . Finally, divide both sides by to comprehensively isolate the variable. Because is positive, the inequality's direction is seamlessly preserved, outputting . The solution is then efficiently graphed on a number line using a left parenthesis at with shading strictly to the right. Under interval notation, the solution is explicitly captured as .
