Answer:

(3x -2) is 498, but that's not one of the answer choices.

Explanation:

Simple if you just break it down.

What do you know about x? That three of them equals 500. Doesn't that sound like you could divide by 3? Let's solve for x and see what happens:

3x = 500 Divide both sides by 3:

x = 500/3

And there it is: 500 divided by 3.

We could punch that in our calculator and get a decimal number out, but let's leave it like that for now.

They want us to evaluate 3x -2, and now we know what x is, so we just plug that value in:

3x - 2 = 3(500/3) - 2 = 500 - 2 = 498

And that doesn't match any of the answer choices, but it's correct for the expressions as you typed them.
