You have just taken a part in a birthday party of your best friend. you went to the party without a gift. but you understood that your friend expected something from you. write a letter for another friend. explain why you went to the party and when, how was the celebration, what you felt after you reached to your home

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

i would think its c but i'm not sure

well i need the text ?   *   *   /

the answer would be c   i believe thats the most reasonable answer
