Answer:
- Infinitely many solutions
Step-by-step explanation:
Given system:
- 8x - 2y = 18
- y = 4x - 9
Solve by substitution:
- 8x - 2(4x - 9) = 18
- 8x - 8x + 18 = 18
- 18 = 18
We got correct equation without variables.
It means the equation is correct for any value of variables, the lines are same and overlap.
So there are infinitely many solutions.
