Question

Nathan wrote the following steps to prove the equation:

Given: 3(x + 2) = 6x + 3
Prove: x = 1

0: 3(x + 2) = 6x + 3 - Given
step1: 3x + 6 = 6x + 3- Distributive Property
step2: 6 = 3x + 3 -Commutative Property of Addition
step3: 3x + 3 = 6- Symmetric Property of Equality
step4: 3x = 3- Subtraction Property of Equality
step5: x = 1- Division Property of Equality

Which step of justification is incorrect, and what should the justification for that step be to solve the equation?

Answer 1

@Hero help please

Answer 2

Answer 3

The justification for step 2 is incorrect. The commutative property deals with the order of your terms. (For example: 2x+3 = 3 + 2x is an example of the commutative property). Now you need to find the correct justification.
