To solve the inequality, start by isolating the term containing x.
-
Add 5 to both sides:
3x−5+5>10+5
3x>15
-
Now, divide both sides by 3:
x>315
x>5

To represent the solution on a number line:
- Draw a horizontal line with numbers marked on it.
- Mark the point at 5 with an open circle to indicate that 5 is not included in the solution (since it is a strict inequality).
- Shade the area to the right of the point 5 to indicate that all values greater than 5 are included in the solution.
