There is something wrong. Double check your problem and make sure you typed the original correctly 8x  12  8x = 12 0=0 The x term drops out completely, this shouldn't happen

yeah i guess so thats why i ased cause i was getting confused

I want to go back to this equation 8x  12  8x = 12 rewritten as 8x  12 = 8x  12 lets get rid of the 12 8x = 8x then the 8's x=x So we can see that x equals all real numbers

This question is written badly. You are positive this is the correct question?

ChmE Group TitleBest ResponseYou've already chosen the best response.1
I'm going to admit that I am confused as to our answer as well. Because x can equal anything which gives us an infinite amount of solutions. x=y/2  3/2 8(y/2  3/2)  4y = 12 4y 12  4y = 12 y can be anything as well I'd say there is any infinite amount of solutions
