Kenny is 5 yearsolderthan Greg. In 5 years, Kenny will be twice as old as Greg is now.How old is Kenny now?
To solve this problem, we can use algebra to represent the information given.
Let's assume Greg's age is x years.
According to the problem, Kenny is 5 years older than Greg, so Kenny's age is (x + 5) years.
In 5 years, Kenny will be twice as old as Greg is now. We can set up the following equation:
(x + 5) + 5 = 2x
Now, let's solve for x to find Greg's current age:
x + 10 = 2x
10 = 2x - x
10 = x
Greg's current age (x) is 10 years.
Now, to find Kenny's current age, we substitute Greg's age into the equation (x + 5):
Kenny's current age = 10 + 5 = 15 years.
Therefore, Kenny is currently 15 years old.
Greg's age now ---- x
Kenny's age now --- x+5
in 5 years:
Greg ---- x+5
Kenny --- x+10
x+10 = 2(x+5)
