Answer: c

This system has infinitely many solutions.

Step-by-step explanation:

Solve by substitution:

1) Solve [tex]y=2x-1[/tex] for [tex]y[/tex]:

[tex]y=2x-1[/tex]

2) Substitute [tex]2x-1[/tex] for [tex]y[/tex] in [tex]2x-y-1=0[/tex]:

[tex]2x-y-1=0[/tex]

[tex]2x-(2x-1)-1=0[/tex]

3) Simplify both sides of the equation:

[tex]0=0[/tex]

Therefore, This system has infinitely many solutions.

Solve by elimination:

You can't solve this system of equations by elimination.

Solve by graphing:

The lines are directly on top of each other, Therefore there are infinitely many solutions.
