Explanation:

Let's pretend you're a doctor and you're interested in lowering blood pressure as a way to reduce the chance that people have heart attacks, and ultimately live better lives. You hear that a drug named atenolol slows down the heart and reduces blood pressure

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

what are you asking? this is gibberish.
