1. Which one sounds better? - origin of a OR diaries of a ? (I feel like the second one is commonly used.)

2. Which is a top notch synonym for the word; Origin?

1) For the first question are any options given ??

2l Dawn ( Dawn is a word that is frequently used so it could be the answer you are looking for )

Hope this helps !

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
