Nick is now seven times as old as Harry. In 6 years, Nick will be five times as old as Harry. How old will Harry be in 6 years? 12 16 18
Harry now = x
Nick now =7x
Nick in 6 years = 7x+6
Harry in 6 years = x+6
Nick in 6 years = 5(Harry in 6 years)
7x+6 = 5(x+6)
So that's the one we want: 7x+6 = 5(x+6)
7x+6 = 5x+30
2x = 24
x =12
so Harry's age in 6 years will be x +6 or 18 years .
