You can put this solution on YOUR website!
let a = his present age
;
15 years from now Isaac will be 8 times as old as he was 6 years ago.
a + 15 = 8(a-6)
a + 15 + 8a - 48
15 + 48 = 8a - a
63 = 7a
a = 63%2F7
a = 9 yrs is his present age

Check this
9 + 15 = 8(9 - 6)
24 = 8(3); confirms our solution of a = 9 yrs
