If you had to choose between 2 things what would they be and which one would you choose??

If I had to choose between food or a phone, I would choose food because I dont want to starve to death and i love to eat!!

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

is this the question?
