Mastering Basic Algebra: Add 7 to Both Sides of the Equation x = 12 Understanding simple algebra is essential for building a strong foundation in mathematics. One common exercise students encounter is manipulating equations by adding the same value to both sides—especially when solving for a variable. In this article, we’ll explore how to apply this fundamental concept using the equation: x = 12 When solving algebraic equations, our goal is to isolate the variable. While in this case, x is already isolated (since x = 12 means “x is equal to 12”), changing both sides by 7 offers a great opportunity to deepen understanding of equation balance and operations.
