Question

Start by substituting 2 for x in the equation.
x + 1 = x + 1
?+ 1 = ? + 1

Answer 1

Let's substitute \( x = 2 \) into the equation \( x + 1 = x + 1 \).

Starting with the left side:

\[
2 + 1 = 3
\]

Now, looking at the right side:

\[
2 + 1 = 3
\]

Both sides of the equation result in \( 3 \), which means that the equation holds true:

\[
3 = 3
\]

So, when we substitute \( 2 \) for \( x \), the equation becomes:

\[
3 = 3
\]

In the format you provided:

\[
? + 1 = ? + 1
\]

We can replace the questions marks with \( 2 \):

\[
2 + 1 = 2 + 1
\]

Overall, the completed equation is:

\[
2 + 1 = 2 + 1
\]
