You can easily check each system of equations by substituting the approximate solution \( (-0.6, 0.8) \) into both equations to see if it holds true. For instance, plug \( x = -0.6 \) and \( y = 0.8 \) into both equations of each pair to find out which one satisfies both conditions. Once you've done the math, you’ll notice that equations can either yield a valid solution or show discrepancies, helping you hone your problem-solving skills. Remember, even if you get an answer that seems close, it's important to double-check your calculations for absolute confidence!
