Answer 1

Answer:

(a) 8 yr

Step-by-step explanation:

Let son present age be x

Father present age = 5x-3

After 5yrs

Father:

(5x-3)+5

Son:

x+5

Three years more than 3 times son's age after 5yrs

[3(x+5)]+3

Equation:

5x+2 = [3(x+5)]+3

5x+2 = 3x+15+3

5x+2 = 3x+18

5x-3x = 18-2

2x = 16

x = 8
