Answer:
<h3>B. Apply the distributive property to get 4x-12=9</h3>Step-by-step explanation:
Isolate the term of x from one side of the equation.
Use the distributive property.
<u>Distributive property:</u>
<u>Expand the form multiply.</u>
4*x=4x
4*3=12
<u>Rewrite the problem down.</u>
4x-12=9
<u>Add by 12 from both sides.</u>
4x-12+12=9+12
<u>Solve.</u>
<u />
<u>Add the numbers from left to right.</u>
9+12=21
4x=21
Divide by 4 from both sides.
4x/4=21/4
<u>Solve.</u>
<u>Divide the numbers from left to right.</u>
x=21/4
21/4=5.25
<u>x=21/4=5.25</u>
- <u>Therefore, the final answer is x=21/4=5.25.</u>
