1. Henry is wrong to say both equations are I correct because they are indeed correct: 12=12 is equivalent to x=x and vise versa. This is because x is a variable and can stand for any number including 12. The ratios of both equations are 1:1 which also makes them equal, because you can simplify them down to 1=1 or 0=0 for example. I hope that makes sense...
