What is -3 - 9n= 42 I can’t be negative

maw [93]

If you were to correctly simplify this equation, the answer would be a negative.

The answer is: n = -5

Here's how I got my answer:

Step 1: Add 3 to both sides. Which leaves us with $-9n=42+3$

Step 2: Simplify $42+3$ to 45. Which leaves us with $-9n = 45$

Step 3: Divide both sides by -9. Which leaves us with $n = -45/9$

Step 4: Simplify $-45/9$ , to get your answer, n = -5.
