1. Subtract 15 from both sides: 9x+15-15≥51-15
2. Simplify: 9x≥36
3. Divide both sides by 9: 9x/9≥36/9
4. Simplify: x≥4
5. Graph the solution: Plot a closed circle at x=4 on the number line and shade the region to the right of 4.
Eric is solving the inequality and graphing the solution. 9x+15≥51 Correctly order the steps he used.
