Question

Please help me !! (no this isnt a test/exam)

Answer 1

Answer:

  infinitely many

Step-by-step explanation:

Add 12-y to both sides of the second equation to put it into standard form like the first equation:

  y +(12 -y) = (x -12) +(12 -y)

  12 = x - y . . . simplify

  x - y = 12 . . . . second equation in standard form

We see this is identical to the first equation. That means every solution of the first equation is also a solution of the second equation. There are infinitely many solutions.
