Step 1: Perform the matrix multiplication on the left side of the equation. The product of a 2 × 2 matrix and a 2 × 1 matrix is a 2 × 1 matrix. 2 & x \\ 5 & 1 4 \\ 3 = (2)(4) + (x)(3) \\ (5)(4) + (1)(3) = 8 + 3x \\ 20 + 3 = 8 + 3x \\ 23 Step 2: Equate the resulting matrix to the given matrix on the right side. 8 + 3x \\ 23 = 17 \\ 17 Step 3: Set the corresponding elements equal to each other to form equations. From the first row: 8 + 3x = 17 From the second row: 23 = 17 The second equation 23 = 17 is a contradiction, which indicates there might be an error in the problem statement or the given matrices. However, assuming the problem intends for us to find x based on the first row's equality, we proceed with solving for x. Step 4: Solve the equation for x. 8 + 3x = 17 Subtract 8 from both sides: 3x = 17 - 8 3x = 9 Divide by 3: x = (9)/(3) x = 3 The value of x is 3. That's 2 down. 3 left today — send the next one.
