The correct Answer is:
To find the value of \( k \) in the equation \( 3x + y = 22 \) given that the point \( (6, k) \) is a solution, we can follow these steps: ### Step 1: Substitute the values of \( x \) and \( y \) We know that the point \( (6, k) \) means \( x = 6 \) and \( y = k \). We will substitute these values into the equation. \[ 3(6) + k = 22 \] ### Step 2: Calculate \( 3(6) \) Now, we calculate \( 3(6) \): \[ 3(6) = 18 \] ### Step 3: Rewrite the equation Now we can rewrite the equation with the calculated value: \[ 18 + k = 22 \] ### Step 4: Solve for \( k \) To isolate \( k \), we subtract 18 from both sides of the equation: \[ k = 22 - 18 \] ### Step 5: Calculate \( k \) Now we perform the subtraction: \[ k = 4 \] ### Final Answer Thus, the value of \( k \) is: \[ \boxed{4} \] ---
