Question

3 years ago, the age of the father was thrice the age of his daughter. Which equation can be used to represent this information?​

Answer 1

Answer:

y=2x-3

where y =father's age

x=daughter's age

Step-by-step explanation:

let's assume Daughter's age is =x

and father's age is =y

3years ago

daughter's age is =x -3

father's age is = y-3

father's age is twice the daughter's age

then

y-3 =2(x-3)

y-3=2x-6

y=2x-3
