Final answer:
To determine whether a value is a solution to an equation, substitute the value into the equation and check if it satisfies the equation.
Step-by-step explanation:
In order to determine whether a value of [variable] is a solution to [equation], you need to substitute the value of [variable] into the equation and see if it satisfies the equation. If the equation is true when the value of [variable] is plugged in, then it is a solution. If the equation is false, then it is not a solution.
For example, if the equation is 2x + 5 = 15 and [variable] = 6, we can substitute 6 for x: 2(6) + 5 = 15. Evaluating this equation, we get 12 + 5 = 15, which is true. Therefore, [variable] = 6 is a solution to the equation.
