Sipho is 6 years older than betty.In 3 year's time sipho will be twice as old as betty.How old is sipho now
s = b + 6
s+3 = 2 (b+3) = 2 b + 6
b+6 +3 = 2 b + 6
3 = b
s = 9
Let's assume Betty's current age is x years.
According to the information given, Sipho is 6 years older than Betty, so his current age would be (x + 6) years.
In 3 years, Betty's age will be (x + 3) years, and Sipho's age will be (x + 6 + 3) years.
According to the second statement, in 3 years' time, Sipho will be twice as old as Betty, so the equation can be formed as follows:
(x + 6 + 3) = 2 * (x + 3)
Expanding the equation:
x + 9 = 2x + 6
Now, we can solve for x:
x - 2x = 6 - 9
-x = -3
Dividing both sides by -1:
x = 3
So, Betty's current age is 3 years.
Substituting this value back into the equation:
Sipho's current age = x + 6 = 3 + 6 = 9 years.
Therefore, Sipho is currently 9 years old.
To find out Sipho's current age, we can solve the problem step by step:
Let's assume Betty's current age is "x" years.
According to the information given, Sipho is 6 years older than Betty. Therefore, Sipho's current age would be "x + 6" years.
In 3 years' time, Betty's age will be "x + 3" years, and Sipho's age will be "x + 6 + 3" years.
According to the problem, in 3 years' time, Sipho will be twice as old as Betty:
x + 6 + 3 = 2(x + 3)
Now, let's solve the equation:
x + 9 = 2x + 6
Moving the variables to one side, we get:
2x - x = 9 - 6
x = 3
Therefore, Betty's current age is 3 years.
To find Sipho's current age, we can substitute the value of x into the equation:
Sipho's current age = x + 6 = 3 + 6 = 9 years
So, Sipho is currently 9 years old.
