Question

Five years hence, the age of Jacob will be 3 times that of his son”. Write a
linear equation taking present age of Jacob as 'x' and his son's age as 'y'.
Explain step by step.​

Answer 1

Answer:

x-5y=12

Step-by-step explanation:

present age of son is y

present age of Jacob is x

after five yrs,

Son's age = y+3

Jacob's age =x+3

According to the question,

x+3= 5(y+3)

x+3=5y+15

x-5y=15-3

x-5y=12
