T= present age of Tshamano

M = present age of Murunwa

We can formulate two equations.

T = 5M (equation 1)

T + 7 = 3(M+7) (equation 2)

Solving the system of equations, we get M = 7 and T = 35

T is 5 times as old as M now.

So T must be divided by 5

the only answer is T age 35 and M age 7

Let Murunwa be x years old. So Tshamano is 5x years old. In 7 years time Murunwas age will be x+7 Tshamanos age will be 5x+7 5x+7=3(x+7) 5x+7=3x+21 2x=14 x=7 So Murunwa is 7 years old and Tshamano is 35 years old.
