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 $\"%281%2F2%29%2A50-5=25-5=highlight%28highlight_green%28highlight%2820%29%29%29\"$ . \n" ); document.write( "
