The sum of the ages of two brothers Kofi and Kweku is 35. If Kofi's age is 2 thirds kwaku's age. Find their ages

Answer 1

Let's assume Kofi's age is x and Kwaku's age is y.
Given that the sum of their ages is 35, we can write the equation:
x + y = 35 ...........(1)
Also given that Kofi's age is 2/3 Kwaku's age, we can write the equation:
x = (2/3)y ..........(2)

To solve these equations, we can substitute equation (2) into equation (1):
(2/3)y + y = 35
(5/3)y = 35
Multiply both sides by 3/5 to isolate y:
y = (35 * 3) / 5
y = 21

Substituting this value back into equation (2), we can solve for x:
x = (2/3)(21)
x = 14

Therefore, Kofi's age (x) is 14 and Kwaku's age (y) is 21.
