When x=4 and y=2 find the value of :
`x-y`

Options

A. 2
B. 3
C. 4
D. 5

Answer

To find the value of \( x - y \) when \( x = 4 \) and \( y = 2 \), follow these steps:

### Step 1: Identify the values of \( x \) and \( y \).
We are given:
- \( x = 4 \)
- \( y = 2 \)

### Step 2: Write the expression for \( x - y \).
The expression we need to evaluate is:
\[ x - y \]

### Step 3: Substitute the values of \( x \) and \( y \) into the expression.
Now, substitute the values:
\[ x - y = 4 - 2 \]

### Step 4: Perform the subtraction.
Now, calculate the result:
\[ 4 - 2 = 2 \]

### Step 5: State the final answer.
Thus, the value of \( x - y \) is:
\[ 2 \]
