Let Bono's dad's age be x. Bono's age is %281%2F2%29%2Ax-5. We have x%2B%281%2F2%29%2Ax-5=70. Simplifying, we get %283%2F2%29%2Ax-5=70. Adding 5 on both sides, we get %283%2F2%29%2Ax=75. Multiplying both sides by 2, we get 3x=150. Dividing both sides by 3, we get highlight%28highlight_green%28highlight%28x=50%29%29%29. So the dad's age is 50. Bono's age is %281%2F2%29%2A50-5=25-5=highlight%28highlight_green%28highlight%2820%29%29%29.
