Respuesta :

x= 3 y= 3
8(3) -2(3)= 18
24 - 6 = 18
y(3) = 4(3) - 9
3 = 12- 9

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.
