Question

Ok this is very dificult for me to answer so....

Answer 1

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!

Answer 2

Answer:

y = -1

Step-by-step explanation:

2x - y = 1

x = 0

y = ?

2(0) - y = 1

-y = 1

y = -1
