Final answer:

The system of linear equations has no solution because the lines represented by the equations are parallel and will never intersect.

Step-by-step explanation:

To solve the system of linear equations:

  1. Arrange the equations in standard form.
    9x - 15y = 24
  2. 6x - 10y = -16
  3. Multiply the second equation by -3 to eliminate x.
    -3(6x - 10y) = -3(-16)
  4. -18x + 30y = 48
  5. Add the two equations together.
    (9x - 15y) + (-18x + 30y) = 24 + 48
  6. -9x + 15y = 72
  7. Combine like terms.
    15y - 9x = 72
  8. Add this new equation to the first equation.
    (15y - 9x) + (9x - 15y) = 72 + 24
  9. 0 = 96

Since the equation 0 = 96 is untrue, there is no solution to the system of linear equations. The two lines represented by the equations are parallel and will never intersect. Therefore, there is no common solution for x and y.
