Finally, look at 100. Start by substituting 100 for x in the equation.

Question

x + 1 = x + 1
? + 1 = ? + 1

Answer 1

To evaluate the equation by substituting \( x = 100 \), you would rewrite it as follows:

\[ 100 + 1 = 100 + 1 \]

Calculating both sides, we get:

\[ 101 = 101 \]

Thus, the equation holds true, confirming the substitution is correct.

So, the substitution can be represented as:

\[ ? + 1 = ? + 1 \]

where both question marks can be replaced by 100:

\[ 100 + 1 = 100 + 1 \]

This is a valid equation.
