Strategy for Determining if a Number is a Solution to an Equation
To determine whether a specific number is a solution to an equation, apply a systematic three-step strategy:
- Substitute: Replace the variable in the equation with the given numerical value.
- Simplify: Independently simplify the mathematical expressions on both sides of the equation.
- Determine truth: Evaluate the resulting simplified statement. If both sides are equal, the statement is true and the number is a solution. If they are not equal, the statement is false and the number is not a solution.
