Answer:
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
