Answer: 
Step-by-step explanation:
The proccedure shown in the problem is applied to solve for x and calculate its value.
One of the equations shown in the problem is:

To solve for x you must_
- Add 6 to both sides of the equations:


- Then you must divide by -3:

Then the answer is: 
A percent is just a fraction.
So take your two numbers and make a fraction with them ... 18/30 .
18 is 18/30 of 30 .
Now, to find the percent that's equivalent to 18/30 ,
first do the division:
18/30 = 0.6 .
Now, to change a decimal into percent,
move the decimal point two places that way ==> .
0.6 = 60% .
18 is 60% of 30 .
