Understanding the Original Expression

The given original expression is ${$ (6x + 3) - (2x + 1)}$. This expression involves the combination of two algebraic expressions, and the goal is to simplify it step by step. To achieve this, we need to apply various mathematical properties to manipulate the expression and arrive at a simplified form.

Step 1: Applying the Distributive Property

The first step in simplifying the given expression is to apply the distributive property. This property states that for any real numbers a, b, and c, the following equation holds: a(b + c) = ab + ac. In the context of the given expression, we can apply the distributive property to expand the first term, (6x + 3), and then subtract the second term, (2x + 1).

Using the distributive property, we can rewrite the expression as:

${$ (6x + 3) - (2x + 1) = 6x + 3 - 2x - 1}$

Step 2: Combining Like Terms

The next step in simplifying the expression is to combine like terms. Like terms are terms that have the same variable raised to the same power. In the expression 6x + 3 - 2x - 1, we can combine the like terms 6x and -2x, as well as the constant terms 3 and -1.

Using the commutative and associative properties of addition, we can rearrange the terms to group like terms together:

${ $6x - 2x + 3 - 1}$

Step 3: Applying the Commutative and Associative Properties

The commutative property of addition states that the order of the terms does not change the result. The associative property of addition states that the order in which we add the terms does not change the result. We can use these properties to rearrange the terms and group like terms together.

Using the commutative and associative properties, we can rewrite the expression as:

${$ (6x - 2x) + (3 - 1)}$

Step 4: Simplifying the Expression

The final step in simplifying the expression is to simplify the terms. We can combine the like terms 6x and -2x, as well as the constant terms 3 and -1.

Using the distributive property, we can rewrite the expression as:

${ $4x + 2}$

Conclusion

In conclusion, we have simplified the given expression one step at a time by applying various mathematical properties. We started with the original expression ${$ (6x + 3) - (2x + 1)}$ and applied the distributive property, combined like terms, and used the commutative and associative properties to arrive at the simplified expression 4x + 2.
