### Example

#### Example 1

Earlier, you were asked about how you could solve .

First, you need to remove the parentheses. You could use the Multiplication Property of Equality or the Distributive Property. Here, it is easier to use the Distributive Property.

Apply the Distributive Property:

Apply the Addition Property of Equality:

Simplify:

Apply the Multiplication Property of Equality:

The solution is .

Checking the solution:

Does Yes, so the answer is correct.

#### Example 2

Solve for when

Apply the Distributive Property:

Combine like terms:

Isolate the variable and its coefficient by using the Addition Property:

Isolate the variable by applying the Multiplication Property:

Checking your solution:

Substitute into

Therefore,
