Analyze the steps Emeril used to solve for the variable to determine if he made an error. In which step did Emeril make an error?

4b + 2b – 3 = –21

1. Combine like terms: 6b − 3 = −21

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

3. Subtraction property of equality: b = −4

Respuesta :

Answer:

Step 2

Step-by-step explanation:

Step 2 should be Addition Property of Equality, to remove -3 from the left equation.

4b + 2b -3 = -21

6b - 3 = -21 (Combined like terms)

6b = -18 (Addition Property of Equality)

b = -3 (Division Property of Equality)
