Answer:
Substitute
Step-by-step explanation:
After you get an answer to an equation, you can substitute your answer into the equation to check to see if it's correct.
Options A and B are steps to complete an equation, not to check it.
Option C should be correct.
Example:
[tex]x+5=16\\x+5-5=16-5\leftarrow \text{Subtraction Property of Equality} \\x=11[/tex]
We can substitute 11 into the equation to check if it's correct.
[tex]11+5=16\\\boxed{16=16}[/tex]
Our answer is correct.
