Question

5 years ago i was thrice as old as my son and 10 years later i shall be twice as old as my son make equation of this and represent it on graph

Answer 1

let my age be x and my son's age be y.
eq.1 ⇒ x-5 = 3(y-5)
x-3y = -10
eq.2 ⇒ x+10 = 2(y+10)
x-2y = 10
subtracting eq.1 from eq.2
y=20 years
x=50 years
