We'll first simplify both sides of the expression to get (simply using the distributive property):

Then, we can simplify a little bit:

To solve for n, we have to isolate it. Let's subtract 3n from both sides to further simplify it:

Then, add 18 to both sides to get the value of n:

And that's your answer. If you have questions on how I got that, feel free to ask!

Answer:
The required equation is 5x - 3 = 12
Step-by-step explanation:
We have to find the equation for the given condition
Let the number be x as given in the equation
Now according to the condition
5 time the Number is 5 *x = 5x
Three less then 5 time the Number would be 5x - 3
And all of it is equal to 12
Which gives us the equation
5x - 3 =12
The required equation is <em>5x - 3 = 12</em>
To find the percent change of something you need to set up a proportion.
amount change (original - new) over new number
x over 100
then cross multiply. Example
25 x
----- ------
50 100
25 x 100 = 2500
2500/50 = 50
So the answer is 50%
