Question

five years ago father was thrice as old as his son. 10 years later, father's age will be twice the age of his son then. represent the above statements by two linear equation

Answer 1

hope this will help you there are the two linear equation in two variable equation I will give you

Answer 2

let the father age be X and the sons age be y
x-5 =( y -5)3
x-5 = 3y-15
x-3y = -10______(i)
x+10 = = (y +10 )2
x+10 = 2 y +20
x-2y =10 _______( ii)
x-3y =-10
from equating both equation
y = 20 years
x-3y =-10
x-60 =-10
x= 50 years
