which of the following equations could be used to determine the value of X

Answer:
D
Step-by-step explanation:
If the original price is x and you deduct 3, you'l have x - 3.
If you buy 4 of them, you multiply that price by 4, giving you 4(x - 3).
Then, if that value is equal to 27, you get 4(x - 3) = 27
Answer:
D
Step-by-step explanation:
We can make each part of the problem into a expression, and combine them.
Part 1: A picture frame that normally costs $x is discounted by 3.
x-3
Part 2: I decided to purchase 4 of the discounted picture frames
4(x-3)
You are buying 4, and each costs x-3.
Part 3: The total cost of the four frames, excluding tax, is $27.
4(x-3)=27
