Answer:

Infinite many solutions.

Step-by-step explanation:

Equation's:

  • 6x+3y=15 __eq 1
  • 8x+4y=20 __eq 2

make y the subject:

eq 1

  • 6x + 3y = 15
  • 3y = 15 - 6x
  • y = 5 - 2x

eq 2

  • 8x + 4y = 20
  • 4y = 20 - 8x
  • y = 5 - 2x

Solve:

y = y

5 - 2x = 5 - 2x

As both sides are equal, the system of equations have infinite solutions.
