Answer:
Daniel is 10 years old presently
Step-by-step explanation:
Since we do not know the ages of both people, we assign variables.
Let Daniel’s present age be d while Willam’s present age is w
Daniel is 8 years older;
Mathematically;
d = w + 8 •••••••••••(i)
In two years time Daniel’s age will be d + 2 while William’s age will be w + 2
We know that Daniel will be 3 times as old as Williams will be in these two years time
Mathematically;
d + 2 = 3(w + 2) ••••••• (ii)
From equation 1, we have w = d-8
we substitute this into equation ii
d + 2 = 3(d-8+2)
d + 2 = 3(d-6)
d + 2 = 3d - 18
3d - d = 18 + 2
2d = 20
d = 20/2
d = 10 years
