Hi guys can you guys help me question's​

Hell

My advice is to upload the course hero!! There is so many different subjects and this exercise 3.5 will help you or check this type of question on .

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'm sorry faith, i dont know how to you on this if you have any other questions hmu okay?
