Let's solve the equation step by step.

1. First, simplify the expression inside the parentheses:
\[
2 + 4 = 6
\]

2. Now multiply by 7:
\[
7 \times 6 = 42
\]

Thus, we have:
\[
7(2 + 4) = 42
\]

You can fill in the blanks like this:
\[
42 = 21 + 21 \quad \text{or} \quad 42 = 40 + 2
\]

It can be any two numbers that add up to 42.
