Final answer:
By setting up a system of equations from the given information, it is determined that a snert is 8 and a snart is 2.
Step-by-step explanation:
The student's question involves setting up a system of equations and solving it. To find the values of a snert and a snart, we can assign variables to them, let's say snert = s and snart = n. The question gives us two pieces of information:
- The difference between a snert and a snart is six: s - n = 6.
- The sum of twice a snert and a snart is eighteen: 2s + n = 18.
We can solve these equations concurrently. First, rearrange the first equation to n = s - 6 and then substitute this into the second equation to get 2s + (s - 6) = 18. Simplifying 3s - 6 = 18, therefore s = 8. Substituting s back into n = s - 6, we find n = 2. So, a snert is 8 and a snart is 2.
