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
+36915 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
