Hope this helps! :)

Answer 2

Present age = 10

Explanation:

Let us assume that,

→ Present age = x

Forming the equation,

→ x + 10 = 4(x - 5)

Now the value of x will be,

→ x + 10 = 4(x - 5)

→ x + 10 = 4x - 20

→ x - 4x = -20 - 10

→ -3x = -30

→ x = -30/-3

→ x = 30/3

→ [ x = 10 ]

Hence, the boy's age is 10.
