Need help solving the problem

Answer:
x [tex]\geq[/tex] 15
Step-by-step explanation:
I like to think of the inequality sign as an equal sign, and solve it like I would any other equation. Subtract 10 from both sides and get x/3 [tex]\geq[/tex] 5. Now multiply 3 on both sides x [tex]\geq[/tex] 15. If you also need the interval notation for this it would be [15,∞).
