Step One: Plug in (x-1) for y in 2x-y = 0
Step Two: Distribute the negative
<u />
Step Three: Add like terms on one side of the equation
Step Four: Subtract 1 from both sides
Step Five: Plug x into one original equation (I chose y=x-1 but you can do either one)
That's the answer to the problem, x = -1, y = -2 (-1,-2)!
Hope this helps!

Answer:
A) y = -2x
B) y = x - 3
Step-by-step explanation:
A) you need to have a negative 'x' coefficient and no y-intercept
B) you need to have a positive 'x' coefficient and a negative y-intercept
Answer:
30=3x
so divide 30 by 3 and you'll get x
It depends how many marbles have been taken out.
N = 48 - x where N is the number that remain after x number of marbles are taken away
