The correct Answer is:
To solve the given equations step by step, we will first address each equation separately and then find the relationship between \( x \) and \( y \). ### Step 1: Solve the first equation The first equation is: \[ (x + y)^2 = 361 \] To solve for \( x + y \), we take the square root of both sides: \[ x + y = \pm \sqrt{361} \] Calculating the square root: \[ \sqrt{361} = 19 \] Thus, we have two cases: 1. \( x + y = 19 \) 2. \( x + y = -19 \) ### Step 2: Solve the second equation The second equation is: \[ 92442 = y^2 + 92361 \] To isolate \( y^2 \), we subtract \( 92361 \) from both sides: \[ y^2 = 92442 - 92361 \] Calculating the right side: \[ y^2 = 81 \] Now, taking the square root of both sides gives: \[ y = \pm \sqrt{81} \] Calculating the square root: \[ \sqrt{81} = 9 \] Thus, we have two cases for \( y \): 1. \( y = 9 \) 2. \( y = -9 \) ### Step 3: Find values of \( x \) for each case of \( y \) Now we will substitute the values of \( y \) back into the equations we derived from the first equation. #### Case 1: \( y = 9 \) Using \( x + y = 19 \): \[ x + 9 = 19 \implies x = 19 - 9 = 10 \] Using \( x + y = -19 \): \[ x + 9 = -19 \implies x = -19 - 9 = -28 \] #### Case 2: \( y = -9 \) Using \( x + y = 19 \): \[ x - 9 = 19 \implies x = 19 + 9 = 28 \] Using \( x + y = -19 \): \[ x - 9 = -19 \implies x = -19 + 9 = -10 \] ### Summary of Solutions From the above calculations, we have the following pairs of \( (x, y) \): 1. \( (10, 9) \) 2. \( (-28, 9) \) 3. \( (28, -9) \) 4. \( (-10, -9) \) ### Step 4: Compare values of \( x \) and \( y \) Now we compare \( x \) and \( y \) for each pair: 1. For \( (10, 9) \): \( x > y \) 2. For \( (-28, 9) \): \( y > x \) 3. For \( (28, -9) \): \( x > y \) 4. For \( (-10, -9) \): \( y > x \) ### Conclusion The relationship between \( x \) and \( y \) varies depending on the specific values derived from the equations. Therefore, we cannot establish a consistent relationship between \( x \) and \( y \).
