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?

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
