Answer:

y=-1

Step-by-step explanation:

We get the equation 2x-y=1, and x=0. Since we know the value of x, that it is equal to 0, we can plug this into the equation for x:

2(0)-y=1

From here, we can multiply 2 by 0 and then divide both sides by -1 to isolate y and get what it's equal to.

0-y=1

-y=1

y=-1

Hope this helps!
