Question

Sarah wrote the following steps to simplify the expression (8x – 6y – 5x).
Step 1: 8x – 5x – 6y; using commutative property of addition
Step 2: (8x – 5x) – 6y; using associative property of addition
Step 3: x(8 – 5 – 6); using distributive property of addition
Step 4: x(-3); simplifying

Which step was incorrect, and what should be the correct step that Sarah should use?
Answers:

Step 2 was incorrect. Correct step: 8x – (5y − 6y); using associative property of addition

Step 3 was incorrect. Correct step: 8x – (5 + 6) y; using distributive property of addition

Step 2 was inc

Answer 1

Step 3 was incorrect, but the correction is also incorrect lol

Answer 2

That is assuming Sarah copied the problem correctly.

Answer 3

so then, this would be it right?Step 3 was incorrect. Correct step: x(8 – 5) – 6y; using distributive property of addition

Answer 4

Yes, thats looks correct. Then of course ultimately you arrive at 3x-6y
