The errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
From the question, we are to determine the errors that Emma made
The given statement is
"The quotient of six and a number, x, is the same as negative two times the difference of x and 4.5"
"The quotient of six and a number, x", can be expressed as
6/x
"Two times the difference of x and 4.5", can be expressed as
2(x - 4.5)
Hence, the errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)

Answer:
-2
Step-by-step explanation:
Let Oliver's number be x.
He multiplies it by 5:
x * 5 = 5x
He then subtracts 26:
5x - 26
Then, he divides by 6:
He then multiplies his original number by 3, and gets the same answer.
This implies that:
Let us simplify this:
Collecting like terms:
Oliver's number is -2.
