in the simple equation 3 + 2y = 8y, both sides actually contain 2y (because 8y is the same as 2y + 6y). Therefore, the 2y on both sides can be cancelled...

{\displaystyle 2x,2y,2z} are even by definition. If x + y = z {\displaystyle x+y=z} , then 2 x + 2 y = 2 ( x + y ) = 2 z {\displaystyle 2x+2y=2(x+y)=2z} ,...
by 2 yields an integer. Let y be this integer (c = 2y). Squaring both sides of c = 2y yields c2 = (2y)2, or c2 = 4y2. Substituting 4y2 for c2 in the first...
