Christopher is 20 years younger than ishaan. ishaan and christopher first met two years ago. fourteen years ago, ishaan was 3 times as old as christopher.
how old is ishaan now?

Let c and i equal the current ages of Christopher and Ishaan.

c=i-20

(i-14)=3(c-14), using c found above in this equation gives you:

i-14=3(i-20-14)  which is

i-14=3i-102  add 14 to both sides

i=3i-88  subtract 3i from both sides

-2i=-88  divide both sides by -2

i=44

Ishaan is now 44 years of age.

check...

c=i-20, so c=24

(i-14)=3(c-14) becomes:

(44-14)=3(24-14)

30=3(10)

30=30
