Definition
Isolating the variable involves manipulating an equation to get the variable alone on one side.
Description
Isolating the variable is a fundamental technique in algebra used to solve equations. It involves performing operations to both sides of an equation to get the variable by itself. For example, solving
2x + 3 = 7
involves subtracting 3 and then dividing by 2 to isolate x, resulting in x = 2.
This technique is widely used in real-world applications such as calculating unknown quantities in physics and engineering problems. Understanding how to isolate variables helps students solve equations efficiently and develop algebraic manipulation skills.
