Hello, I was solving for the following:
6 - 3n = 12...
I got the answer (-2).
I'm having trouble verifying my answer. Please help
so plug in your answer
6 - 3(-2) = 6 - (-6) = 12
(Please ignore this) For my reference, it is 3. b
Hi, thanks so much. I guess I got confused by the negative integer addition
To verify your answer, you can substitute the value of n that you obtained (-2) back into the equation and check if it holds true.
Let's substitute n = -2 into the equation 6 - 3n = 12:
6 - 3(-2) = 12
Simplifying:
6 + 6 = 12
12 = 12
Since the equation simplifies to a true statement, 12 = 12, we can conclude that your answer, n = -2, is correct.
Alternatively, we can solve the equation algebraically:
Given equation: 6 - 3n = 12
First, we want to isolate the variable n, so we'll move the constant term (-6) to the other side of the equation:
6 - 6 - 3n = 12 - 6
-3n = 6
Next, we divide both sides of the equation by -3 to solve for n:
(-3n)/-3 = 6/-3
n = -2
This method confirms that your solution n = -2 is correct.
