Lebo is four years older than Sello.In six years' time, the sum of their ages will be 40.How old is Lebo [hint: let Lebo's age be =x]
S = x - 4
(x+6) + ( S+6) = 40
Substitute x-4 for S and solve for x.
Sello is X years old.
Lebo is x+4 years old.
six years later:
x+6 + (x+4)+6 = 40.
2x + 16 = 40,
X = 12.
x+4 = 12+4 = 16 years = Lebo's age.
To solve this problem, we'll need to set up a system of equations based on the information given.
Let's assign variables to represent Lebo and Sello's current ages:
Let Lebo's age be x
Since Lebo is four years older than Sello, Sello's age would be x - 4.
In six years' time, Lebo will be x + 6 years old, and Sello will be (x - 4) + 6 years old.
We are told that the sum of their ages in six years will be 40, so we can write the equation:
(x + 6) + ((x - 4) + 6) = 40
Now, we can solve for x:
x + 6 + x - 4 + 6 = 40
2x + 8 = 40
2x = 40 - 8
2x = 32
x = 32/2
x = 16
Therefore, Lebo is currently 16 years old.
