Question

I don’t know how to give extra point because I’m new to this app but I would appreciate it if you could help

Answer 1

Answer:

n=-4

Step-by-step explanation:

First, subtract 3n on both sides. This results in -3=n+1. Then, subtract 1 on both sides. The answer is n=-4.

Answer 2

Answer:

B

Step-by-step explanation:

We have the equation:

$3n-3=4n+1$

Let's solve for n. To do so, we want to isolate it.

Let's use the subtraction property of equality to subtract 3n from both sides:

$(3n-3)-3n=(4n+1)-3n$

The left side will cancel...

$-3=(4n+1)-3n$

Subtract on the right:

$-3=1n+1$

Remember that 1n is the same as just n. So:

$-3=n+1$

Now, let's use the subtraction property of equality again to subtract 1 from both sides:

$(-3)-1=(n+1)-1$

The right side will cancel. Subtract on the left:

$-4=n$

Symmetric property:

$n=-4$

So, our answer is B.

And we're done!
