Beyond the Answer

To determine if \( (4,2) \) is a solution of the system, we can substitute \( x = 4 \) and \( y = 2 \) into both equations. For the first equation \( y = x - 2 \): \( 2 = 4 - 2 \) which simplifies to \( 2 = 2 \). This is true! For the second equation \( y = 3x + 4 \): \( 2 = 3(4) + 4 \) simplifies to \( 2 = 12 + 4 \) or \( 2 = 16 \). This is false! Since the second equation does not hold, \( (4,2) \) is not a solution of the system. The answer is (B) No.
