Answer 1

B) combine like terms

Explanation:

When you combine like terms, you have to consider all and need to plug in your answer into the original equation to check.

Answer 2

Substitute

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:

`x+5=16\\x+5-5=16-5\leftarrow \text{Subtraction Property of Equality} \\x=11`

We can substitute 11 into the equation to check if it's correct.

`11+5=16\\\boxed{16=16}`

Our answer is correct.
