Example: Solving and Graphing 9y+2(y+6)>5y249y + 2(y + 6) > 5y - 24

To solve the multi-step linear inequality 9y+2(y+6)>5y249y + 2(y + 6) > 5y - 24, start by distributing to simplify the left side, which generates 9y+2y+12>5y249y + 2y + 12 > 5y - 24 and combines smoothly to 11y+12>5y2411y + 12 > 5y - 24. Subtract 5y5y from both sides to responsibly collect the variables on the left, leading directly to 6y+12>246y + 12 > -24. By subtracting 1212 from both sides, the constants are gathered firmly on the right, resulting in 6y>366y > -36. Finally, divide both sides by 66 to comprehensively isolate the variable. Because 66 is positive, the inequality's direction is seamlessly preserved, outputting y>6y > -6. The solution is then efficiently graphed on a number line using a left parenthesis at 6-6 with shading strictly to the right. Under interval notation, the solution is explicitly captured as (6,)(-6, \infty).
