We have that we are solving for the equation:
To start solving it, we need to subtract x to both sides of the equation. This property is Subtraction Property of Equality:
In the next step, we use the Addition Property of Equality, since we have to add 6 to both sides of the equation:
And the last step is to use the Division Property of Equality since we need to divide by 2 to both sides of the equation:
In summary, the order of each of the reasons for each step is (see all the steps above):
• The original equation is 3x - 6 = x + 4
,
• After applying the Subtraction Property of Equality, we got 2x - 6 = 4
,
• After applying the Addition Property of Equality, we got 2x = 10
,
• After applying the Division Property of Equality, we finally got x = 5.
