Example Question - isolating variables in equations

Solving a Linear Equation for x

To solve the equation 2x + 3 = 13 for x, follow these steps: 1. Subtract 3 from both sides of the equation to isolate the term with x: 2x + 3 - 3 = 13 - 3 This simplifies to: 2x = 10 2. Divide both sides of the equation by 2 to solve for x: 2x / 2 = 10 / 2 This simplifies to: x = 5 So the solution is x = 5.
