Answer 2

Simplifying the Expression

To simplify the expression (12 + 7x) - (1 - 3a), we can use the distributive property to remove the parentheses and then combine like terms.

The steps to simplify the expression are as follows:

1. Distribute the negative sign inside the second set of parentheses. 2. Combine like terms.

Let's go through these steps.

1. Distribute the Negative Sign: - (12 + 7x) - (1 - 3a) becomes 12 + 7x - 1 + 3a.

2. Combine Like Terms: - Combine the constants (12 and -1) and the terms with 'x' and 'a' respectively.

So, the simplified expression is: 12 - 1 + 7x + 3a.

Now, the simplified expression is 11 + 7x + 3a.

This is the simplified form of the given expression.
