y=2x−1 5x−4y=1 is (1,1)(1,1) a solution of the system?

The ordered pair is a solution of the system of equations

Step-by-step explanation:

we have

-----> equation A

-----> equation B

we know that

If a ordered pair is a solution of the system of equations, then the ordered pair must be satisfy both equations of the system

Verify equation A

Substitute the value of x and the value of y in the equation and then compare

For

-----> is true

Verify equation B

Substitute the value of x and the value of y in the equation and then compare

For

-----> is true

therefore

The ordered pair is a solution of the system of equations

b, i believe, but not sure.
