`x-1/2a=0`
If x = 1 in the equation above, what is the value of a ?

Explanation

To solve the equation \( x - \frac{1}{2}a = 0 \) for \( a \) when \( x = 1 \), follow these steps:

### Step 1: Substitute \( x = 1 \) into the equation
Start with the original equation:
\[ x - \frac{1}{2}a = 0 \]
Substituting \( x = 1 \):
\[ 1 - \frac{1}{2}a = 0 \]

### Step 2: Isolate the term involving \( a \)
To isolate \( \frac{1}{2}a \), add \( \frac{1}{2}a \) to both sides:
\[ 1 = \frac{1}{2}a \]

### Step 3: Solve for \( a \)
To eliminate the fraction, multiply both sides by 2:
\[ 2 \cdot 1 = a \]
This simplifies to:
\[ a = 2 \]

### Final Answer
Thus, the value of \( a \) is:
\[ \boxed{2} \]
