Question

Currently, Vanessa is twice as old as Chris. Eight years ago, Vanessa was six times as old as Chris. How old is Chris now?​

Answer 1

Currently, Chris is 10 years old. Vanessa is 20.

Explanation:

2x = 6x - 8, so x = 2. Meaning Chris was 2 years old 8 years ago. So if Chris was 2, that means Vanessa was 12. Add 8 to both sides, 2 + 8 and 12 + 8, we get the result of Chris being 10, and Vanessa is 20. Which does fit the twice as old part.

Answer 2

Chris is currently 10

Explanation:

I'll be honest, I looked this up so sorry for stealing the points, but use the letter v to represent vanessa and c for chris

If vanessa is twice chris' age, then v=2c

Your other equation would be (v-8)=6(c-8)

Use these two equations to solve for c through a system of equations and get c = 10 or Chris' current age is 10
