Answer:
Hidhri is 20 years old
Kawthar is 15 years old
Step-by-step explanation:
Hidhri is x years old
Kawthar is y years old
x = 5 + y (Hidhri is five years more than Kawthar)
x + y = 36 (sum of their age is 36 years)
Substitute:
(5 + y) + y = 36
5 + y + y = 36
5 + 2y = 36
2y = 36 - 5
2y = 31
y = 31 ÷ 2
y = 15.5
Kawthar is 15 years old.
Since Hidhri is five years more,
15 + 5 = 20
Hidhri is 20 years old.
