Identify Equation: Identify the equation to solve: 2x + 1 = 5. We need to find the value of x that makes this equation true. Subtract to Isolate: Subtract 1 from both sides of the equation to isolate the term with x. This gives us 2x + 1 - 1 = 5 - 1. Perform Subtraction: Perform the subtraction: 2x = 4. Now, the equation is simplified, and we have isolated the term with x on one side. Divide to Solve: Divide both sides of the equation by 2 to solve for x. This gives us 2x / 2 = 4 / 2. Perform Division: Perform the division: x = 2. We have found the value of x that makes the original equation true.
