Answer:

0

Step-by-step explanation:

The expression we are given is (2 * x - 4).

We need to find the value of expression when x = 2.

Let's substitute 2 in as x.

Now our expression is (2 * 2 - 4).

First, let's multiply our 2 with our substituted 2.

1.  2 * 2 = 4

We're left with (4 - 4).

Finally, let's evaluate this expression.

2.  (4 - 4) = 0.

Our answer is 0.

So (2 * x - 4) when x = 2 is 0.

<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>

If the y would be equal to 0, everything would then just depend if you add or subtract the x:

y-x=-3\\\\y+x=3\\\\y= 0\\x=3\\\\then:\\\\0-3=3\\and\\0+3=3

Now the first answer could be correct for:

y-x=-3\\because\ if\\\\y=-3 \ and \ x=0 \ then\\-3-0=-3

However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)
