Identify Equation Type: Identify the type of equation.The equation 2x=x+2 is a transcendental equation because it involves an exponential function and a polynomial function. There is no algebraic method to solve this type of equation directly. We will attempt to find a solution by inspection or simple substitution.
Check Obvious Solutions: Check for obvious solutions.We can check if small integer values of x satisfy the equation. Let's start with x=0.20=0+21=2This is not true, so x=0 is not a solution.
Check x=1: Check the next integer value for x. Let's try x=1. 21=1+22=3 This is also not true, so x=1 is not a solution.
Check x=2: Check the next integer value for x. Let's try x=2. 22=2+24=4 This is true, so x=2 is a solution.
