For what value of c, the linear equation 2x+cy=8 has equal values of x and y for its solutions ?

Explanation

To find the value of \( c \) such that the linear equation \( 2x + cy = 8 \) has equal values of \( x \) and \( y \), we can follow these steps:

### Step 1: Set \( x \) equal to \( y \)
Since we want the values of \( x \) and \( y \) to be equal, we can set \( x = y \).

### Step 2: Substitute \( y \) with \( x \)
Replace \( y \) in the equation with \( x \):
\[
