Since the random variable x is continuous, we can make use of linear operator
E(X*) = E(5 - 3X)
X* = E(5) - E(3X)
X* = 5 - 3E(X)
X* = 5 - 3(2.71)
X* = -3.13
The mean of the transformed variable is -3.13.<span />
Add 3 to both sides, this gives y + 3 = db
then divide both sides by b, this gives (y + 3)/b = d

9q + q - 6p - q
9q+q-q-6p - rearranging
10q-q-6p
Pretend that there is a -1 in front of -q
10q-1q-6p
9q-6p
Answer:
9q-6p or -6p+9q
