one solution no solution or infinitely many solutions. Explain for full marks.

 

y = 2x - 5

4x - 2y = 10

 

5x - y = 4

-5x + y - 4 = 0

Those are ALL equations of lines and thus have infinte solutions .....   or did you mean those as SETS of equations?

 

The first set is the same equation....infinite solutions

  the second set is two different lines ...parallel lines   no solutions
