Brianna's thinking is incorrect.
Expessions A, and C. are equivalent.
For C, you add 5x and x together (because they have the same variable) to get 6x - 4.
For A, you subtract 9x and 3x (because they have the same variable) to get 6x- 4.
Answer:
The answer is 4.
Step-by-step explanation:
In order to get this answer you have to use inverse operations. The inverse operation for multiplication is always division. So, you have to solve the equation 7.5 ÷ 1.75. When getting the answer to that (the answer of the equation above), you get <em>n</em>, as it is only a one-step equation. I hope I could help you.
