To solve for \( a \) in the equation \( P = 2a + b \), you can follow these steps:
1. Start with the equation:
\[
P = 2a + b
\]
2. Subtract \( b \) from both sides:
\[
P - b = 2a
\]
3. Now, divide both sides by 2 to isolate \( a \):
\[
a = \frac{P - b}{2}
\]
So, the length of the leg of the triangle \( a \) is given by:
\[
a = \frac{P - b}{2}
\]
