Let's solve the expression step by step.
First, calculate the value inside the parentheses:
\[
3.2 - 5.1 = -1.9
\]
Now, substitute that back into the original subtraction:
\[
7.9 - (-1.9)
\]
Subtracting a negative value is the same as adding the positive value:
\[
7.9 + 1.9 = 9.8
\]
Thus, the result of the subtraction \( 7.9 - (3.2 - 5.1) \) is:
\[
\boxed{9.8}
\]
