Hello!

Answer:

1.
\boxed{W=-6}

*The answer must have A NEGATIVE SIGN ONLY!*

2.
\boxed{B=15}

*The answer must have A POSITIVE SIGN ONLY!*

3.
\boxed{N=-44}

*The answer must have a NEGATIVE SIGN ONLY!*

Explanation:

1. 9w=-54

First, you divide by 9 both sides of an equation.

9w/9=-54/9

Simplify.

-54/9=-6

W=-6 is the final answer.

2. b-12=3

First you add by 12 both sides of an equation.

b-12+12=3+12

Add by the numbers from left/right.

3+12=15

b=15 is the final answer.

__________________________________________

3. n/4=-11

First you multiply by 4 both sides of an equation.

4n/4=4(-11)

Multiply by the numbers from left/right.

4*-11=-44

n=-44 is the final answer.

Hope this helps you!

Have a great day! :)
