Question

If y=x and y=x+2 are the same, then how many solutions does it have

Answer 1

Answer:

  none

Step-by-step explanation:

"they are the same" translates to ...

  x = x +2

  0 = 2 . . . . . . subtract x from both sides. — a FALSE statement

There are no values of x or y that make this true.

_____

The two equations describe parallel lines, so they cannot be "the same." There are no points of intersection.
