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.
