To solve for \( b \) in the equation
\[
A = \frac{1}{2} (a + b),
\]
follow these steps:
1. **Multiply both sides by 2** to eliminate the fraction:
\[
2A = a + b.
\]
2. **Rearrange the equation** to isolate \( b \):
\[
b = 2A - a.
\]
Thus, the solution for \( b \) is
\[
b = 2A - a.
\]
\[
A = \frac{1}{2} (a + b),
\]
follow these steps:
1. **Multiply both sides by 2** to eliminate the fraction:
\[
2A = a + b.
\]
2. **Rearrange the equation** to isolate \( b \):
\[
b = 2A - a.
\]
Thus, the solution for \( b \) is
\[
b = 2A - a.
