Question

"Five years from now, father's age will be 3 times the age of son. Five years ago, father's age was 7 times as old as his son". Represent this situation as a pair of linear equations in x and y.​

Answer 1

Answer:

let age of son be x and father be y

$y + 5 = 3(x + 5)$

$y - 5 = 7(x - 5)$

hope this will help you

Answer 2

Answer:

after five years

son's age is x¹ years

father age is 3x¹ years

before five years

son's age was x²

father age was 7x²

hence, equation is

x²- 10 = x¹ ( son's age)

7 x² - 10 = ( father age)

NOTE. X¹ AND X² ARR JUST TO REPRESENT THE AGES AND ARE

NOT THE POWERS
