How do you simplify?

Simplifying is basically just reducing . If you're simplifying a fraction you should make both the numerator and denominator divisible by the same number . For example if you're simplifying 20 / 12 . You are able to divide 20 by 4 and 12 by 4 . By doing that you'll get 5 / 3 which is is the simplified version of 20 /12 . 


Now to simplify equations it can either be finding the answer or reducing the equation as much as you can until there is nothing else to reduce . For example , for the equation


2x + 5x + 2y + 10y = 20y + 9 + 10 First let's add the 2x and the 5x together


By adding 2x and 5x together, you should get


7x + 2y + 10y = 20y + 9 + 10 now , let's add the 2y with the 10y 


By adding the 2y and the 10y together , you should get


7x + 12y = 20y + 9 + 10 now let's combine the 9 and 10 on the right side of the equation 


By combining the 9 and the 10 , you should get 


7x +12y = 20y + 19 now subtract 20y on both sides , that way all the " y " would be together


By doing that , you should get 


7x - 8y = 19 Now this is basically the reduce equation of the earlier equation , but you can also subtract the 19 on both sides making the equation equal to 0 , so it would be 7x - 8y -10 = 0 . It basically depends on what the questions asks you to do .

What is the main function of the fool in "King Lear"? What is the secondly function?

The fool as a character is confusing, but part of this is the difference between the 1600s and today, as well as the difference in place. If...
