To evaluate the expression \( 10 + 3|1 - 7| \), we follow the order of operations:
1. Calculate \( |1 - 7| \):
\[
1 - 7 = -6 \quad \text{and} \quad |-6| = 6
\]
2. Substitute back into the expression:
\[
10 + 3|1 - 7| = 10 + 3 \times 6
\]
3. Calculate \( 3 \times 6 \):
\[
3 \times 6 = 18
\]
4. Add this to 10:
\[
10 + 18 = 28
\]
Thus, the value of the expression is \( \boxed{28} \).
