Make y the subject in both equations

[tex]2x-y=7 [/tex]

[tex]-y=-2x+7 [/tex]

[tex] y=2x-7[/tex]

For the second equation

[tex] y=2x+3 [/tex]

The two equations are parallel because they have the same gradient or slope but different y intercepts.

This type of equations have no solution because they will never intersect.

[tex] <B> NO SOLUTION </B> [/tex]

The correct answer is C
