Answer:
29/6
Step-by-step explanation:
The expression that we have to evaluate in this problem is
for .
First of all, we re-arrange the expression. We know that:
- The product of a positive number (+) and a negative number (-) is negative (-)
- The product of a negative number (-) and a negative number (-) is positive (+)
So we can rewrite the expression as
Also, we can combine the two numerical terms:
Therefore the expression becomes
Now we can substitute , and we find:
