In the equation x – 4y = 2, for what value of x will y = 0?

Question

whpalmer4 · Answer

$$x-4y=2$$You want to find the value of $x$ when $y=0$, so put $y=0$ in the equation and solve for $x$:
$$x-4(0) = 2$$$$x-0=2$$$$x=$$

anonymous · Answer

so its -2 right?

whpalmer4 · Answer

$$x-0=2$$From that you get $x=-2$?

whpalmer4 · Answer

Does the equation work if you substitute in $x=-2,y=0$?  Let's find out:
$$x-4y=2$$$$-2-4(0) = 2$$$$-2-0=2$$$$-2=2$$Uh, no.

so its 2 0r -2

whpalmer4 · Answer

You have some number, $x$.  

Here's an equation:
$$x - 0 = 2$$

Translated into words, that reads: "take your number, $x$, and subtract 0 from it.  The result is 2."

What is the only value that $x$ can have to make that sentence true?

2-0=2

Yes.

$$x-4y=2$$$$2-4(0)=2$$$$2-0=2$$$$2=2$$
