Now for Eight years ago (subtract 8 from both people age)
so , vikram becomes (v-8) and Marisol becomes M-8
Now, their relationship is
M-8 = 3(v-8)-6

hmmmm. Why would I not triple Vikramâ€™s age then subtract 8? when I distribute the 3 to the 8 years is that not really just subtracting 24 years from the age?

Let Vikram age be v â€”> This is his current age
And because the relationship was give for 8 years back and at that time Vikram was (v-8) years old. â†’ this is Vikram age 8 years ago, thus youâ€™ve to distribute that 3 over (v-8) and not just v.
