Question

Emeril solved this equation using the steps shown below:

Answer 1

Answer:

Step 2: He should have added 3 to, rather than subtracting 3 from, both sides.

Step-by-step explanation:

1. Combine like terms: 6b − 3 = −21  

2. Subtraction property of equality: 6b = −24  

Here he has to add 3 on both sides, to isolate the variable term.

Therefore, answer is Step2)  He should have added 3 to, rather than subtracting 3 from, both sides.

Hope this will helpful.

Thank you.

Answer 2

He made an error in step 2 because you are supposed to do the inverse operations on the -3 which would be +3.
