"Windows cannot open this program" Copy and paste it here.

Ok, just give me a moment.

Kelly wrote the following steps to prove the equation: Given: 2(x – 3) = 5x + 3 Prove: x = –3 Step Mathematical Statement Justification 0 2(x - 3) = 5x + 3 Given 1 2x - 6 = 5x + 3 Distributive Property 2 – 6 = 3x + 3 Subtraction Property of Equality 3 3x + 3 = –6 Transitive Property of Equality 4 3x = –9 Subtraction Property of Equality 5 x = –3 Division Property of Equality Which step of justification is incorrect, and what should the justification for that step be to solve the equation? Step 1; Commutative Property of Multiplication Step 2; Associative Property of Addition Step 3; Symmetric Property of Equality Step 4; Combine Like Terms

8. Compassionate

There is some stuff missing.

9. JulietLRK

That's what they gave me.

10. Compassionate

"Distributive property." No need for that. H should have added the like terms.

11. Compassionate

Actually, the property of equality or adding like terms; It's a matter of how you go at it.

12. JulietLRK

So its the second option.

13. JulietLRK

Thank you!!!!!!

14. Compassionate

Watch, I'm going to add like terms. 2x - 6 = 5x + 3 2x - 5x = +6 + 3 3x = 9 x = 3

15. JulietLRK

Thanks!!! :) I now understand fully!

16. Compassionate

All though both operations are correct; they're only going to ask for one, right?

17. JulietLRK

Yes.

18. Compassionate

Is it multiple option or something you write to report?

19. JulietLRK

multiple choice
