Solution:

Simplify the RHS:

  • 24 < 4x - 3 + 5x + 6
  • => 24 < 9x - 3 + 6

Further simplify the RHS:

  • => 24 < 9x + 3

Subtract 3 both sides:

  • => 24 - 3 < 9x

Simplify the LHS:

  • => 21 < 9x

Divide both sides by 9:

  • => 21/9 < 9x/9
  • => 7/3 < x

Switch signs:

  • => x > 7/3

Now, graph the line.
