Step-by-step explanation:
Solve by substitution:
1) Solve
for
:
![y=2x-1](https://tex.z-dn.net/?f=y%3D2x-1)
2) Substitute
for
in
:
![2x-y-1=0](https://tex.z-dn.net/?f=2x-y-1%3D0)
![2x-(2x-1)-1=0](https://tex.z-dn.net/?f=2x-%282x-1%29-1%3D0)
3) Simplify both sides of the equation:
![0=0](https://tex.z-dn.net/?f=0%3D0)
Therefore, This system has infinitely many solutions.
Solve by elimination:
You can't solve this system of equations by elimination.
Solve by graphing:
