Example: Solving and Graphing
To solve the linear inequality , first aggressively apply distribution to clarify the left side into . Combine associated like terms to confidently gather . To draw the variables collectively onto the left, logically subtract from both sides, producing . Add to both sides to purposefully reposition the constant onto the right, obtaining . Divided by , the variable is neatly isolated. Since is positive, the inequality symbol acts unchanged, concluding firmly with . This exact solution is graphed featuring a left parenthesis reliably at followed by distinct shading constantly to the right. In interval notation, the entire outcome is formally noted as .
