Solve each equation using inverse operations: 1. 9w = -54 2. b - 12 = 3 3. n/4 = -11
katovenus [111]

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!*

Step-by-step explanation:

1. 9w=-54

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

9w/9=-54/9

Simplify.

-54/9=-6

<u><em>W=-6 is the final answer.</em></u>

____________________________________

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

<u><em>b=15 is the final answer.</em></u>

__________________________________________

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

<u><em>n=-44 is the final answer.</em></u>

_____________________________

Hope this helps you!

Have a great day! :)

:D
