Answer 1

To make the expression \( -7 + [?] + b \cdot 1 \) equivalent to \( b \), let's rewrite the expression:

\[ -7 + [?] + b \]

We want this to equal \( b \). So we can set up the equation:

\[ -7 + [?] + b = b \]

Subtracting \( b \) from both sides, we get:

\[ -7 + [?] = 0 \]

This means that:

\[ [?] = 7 \]

Thus, the number that makes the expression equivalent to \( b \) is 7.
