Question 1094536: 12 years old Ryan is three times as old as his brother Jeffrey,how old Will Ryan be when he is twice as old as his brother Jeffrey Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Ryan is 12; Jeffrey is 4. Let n be the time before Ryan is twice Jeffrey's age. Then:
12+n=2(4+n)
12+n=8+2n
n=4
In 4 years Ryan will be 16; and Jeffrey will be 8
