In the realm of mathematics, particularly when dealing with algebra, the concept of equivalent equations is fundamental. Equivalent equations are equations that, despite potentially looking different, share the same solution set. This means that if a certain value for a variable satisfies one equation, it will also satisfy its equivalent forms. Identifying equivalent equations is crucial for simplifying problems and finding solutions more efficiently. This article delves into how we can use properties of equality to rewrite equations while preserving their solutions. We'll focus on the given equation and explore which of the provided options are equivalent to it. We'll achieve this by applying algebraic manipulations such as combining like terms, adding or subtracting the same value from both sides, and multiplying or dividing both sides by the same non-zero value. These operations, rooted in the properties of equality, ensure that the balance of the equation is maintained, and thus, the solution set remains unchanged.
