The equation is \(58 + 6x = 40 + 8x\). Solving this gives \(x = 9\), meaning each school got 9 correct answers in the final round.

To solve this problem, let's first set up the equation based on the given information. If School A gets \(x\) correct answers, then it also gives \(x\) incorrect answers. For School A, the score from the final round will be calculated as follows: starting points (58) + points from correct answers (8x) - points from incorrect answers (2x). This gives us the equation for School A's final score as: \[ \text{Score of School A} = 58 + (8x - 2x) = 58 + 6x \] For School B, since they get the same number of correct answers \(x\) and no incorrect answers, their final score becomes: \[ \text{Score of School B} = 40 + 8x \] Since the two schools end up tied, we can set their scores equal to each other: \[ 58 + 6x = 40 + 8x \] Now, let’s solve for \(x\): 1. Rearranging the equation gives: \[ 58 - 40 = 8x - 6x \] 2. This simplifies to: \[ 18 = 2x \] 3. Dividing by 2, we find: \[ x = 9 \] So, both schools answered 9 questions correctly in the final round! Now, School A answered 9 correct and 9 incorrect, while School B answered 9 correct and 0 incorrect. In summary, School A has a final score of \(58 + 6(9) = 102\), and School B has a final score of \(40 + 8(9) = 102\), confirming they indeed end up tied!
