What is the effect of the rrepetition of your

Depending on the text, the repetition of "your" can make the text feel as if it is more focused on you, or it could be influential. It can also make the reader feel as if it is their job to do something if "your" is used as a call to action.

hooch has about 3% alcohol content so the 5 gallon 90% platinum vodka would be stronger because it has a higher alcohol content then hooch.  

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
