Simplifying Algebraic Expressions: Key Concepts and Techniques

What is the main difference between solving equations and simplifying expressions?

• Both involve rewriting the expression in its simplest form.

• Solving equations involves finding the value of the variable, while simplifying expressions involves rewriting the expression in its simplest form.

• Solving equations involves rewriting the expression in its simplest form, while simplifying expressions involves finding the value of the variable.

• Both involve finding the value of the variable.
