My age is four times the difference of my age after four years and my age three years back .
:
Let a = your present age
:
Write an equation for exactly what it says:
a = 4[(a+4) - (a-3)]
a = 4(a + 4 - a + 3)
a = 4(a - a + 4 + 3)
a = 4(7)
a = 28 is your present age
:
:
See if that flies
a = 4(32-25)
a = 4(7); confirms our solution of 28 yrs
