If 4y is 9 greater than the sum of y and 3x, by how much is greater than x?
Answer Details
Let's start by translating the sentence into an equation:
4y = 9 + y + 3x
We can simplify this equation by subtracting y from both sides:
3y = 9 + 3x
Now, let's isolate x by subtracting 9 from both sides and then dividing by 3:
x = (3y - 9)/3 = y - 3
So we see that x is 3 less than y. Therefore, the answer is (A) 3.
