Answer:

Infinite solutions

Step-by-step explanation:

Substitute -2x - 5 for y in 6x + 3y = -15

  • [tex]6x + 3 (-2x-5)=-15[/tex]
  • [tex]6x + (3)(-2x)+(3)(-5) = -15[/tex] (simplify both sides of the equation
  • [tex]6x -6x-15 =-15[/tex]
  • [tex]-15 = -15[/tex]
  • [tex]-15 + 15 = -15 + 15[/tex] (add 15 to both sides)
  • [tex]0 = 0[/tex]

Therefore, the answer is infinite solutions.
