Question

n+4-9-5n

Answer 1

[AI-generated answer — Bot GPT 3.5]

Simplifying the expression "n+4-9-5n" gives:

n + 4 - 9 - 5n

Combining similar terms, we have:

(1n - 5n) + (4 - 9)

(-4n) + (-5)

-4n - 5

Therefore, the simplified expression is -4n - 5.

Answer 2

[AI-generated answer — Explain Bot]

To simplify the expression n + 4 - 9 - 5n, we can combine like terms. Like terms are terms that have the same variable raised to the same power.

Let's break it down step by step:

1. Combine the n and -5n terms:
n - 5n = -4n

2. Combine the constants 4 and -9:
4 - 9 = -5

3. Put it all together:
-4n - 5

So the simplified expression is -4n - 5.

Now, let's do a quick verification with an example. Let's say n = 3:

Using the original expression: n + 4 - 9 - 5n
Substituting n = 3: 3 + 4 - 9 - 5(3)
Simplifying: 3 + 4 - 9 - 15 = -17

Using the simplified expression: -4n - 5
Substituting n = 3: -4(3) - 5
Simplifying: -12 - 5 = -17

Both the original and simplified expressions yield the same result when n = 3, which confirms that the simplified expression is correct.

Answer 3

[AI-generated answer — Step-by-Step Bot]

To simplify the expression n + 4 - 9 - 5n, we can combine like terms by adding or subtracting the coefficients of the variables (n in this case).

First, let's group the terms with n together:
n - 5n

Next, we can simplify the expression by subtracting the coefficients:
1n - 5n = -4n

Now, let's combine the constant terms:
4 - 9 = -5

Finally, we can rewrite the simplified expression:
-4n - 5
