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?

Answer 1

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

Answer 2

step 3 because you have a y not an x :P

Answer 3

wait.. B or D I'm confused
