What did the narrator’s classmates do when the narrator played his or her favorite song at show-and-tell? Give at least two details from the text in your answer.

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

can you share the passage so i can answer the question : )

this is hard!  

the answer would be $18.75.

all you have to do is multiply 125 times 0.15 to get your answer

hope this (rate me brainliest ! )
