Equivalent? Explain

3x - 10 and 3(x - 10)

No. If simplified they are not the same (or if x=1 they are -7 and-27)

200

Equivalent?

2x + 3 - 5x - 4 and -1 - 3x

Yes. When simplified they are the same.

300

Equivalent?

-2(x - 5) and -2x + 10

Yes. They are both -2x+10 when simplified.

(Put in any number for x and they will equal the same thing.)
