Final answer:
To determine the value(s) for the variable to make an algebraic equation true, substitute the given value and check if it satisfies the equation.
Step-by-step explanation:
In order to determine what value(s) for the variable would make the algebraic equation a true number sentence, we need to substitute the given value for the variable in the equation and check if it satisfies the equation.
For example, let's consider the equation d = 36. We substitute 36 for d in the equation and check if it is true. So, d = 36 is a true number sentence.
