Reciprocal of 19/3 is 3/19. You just flip the fraction. To find a reciprocal of a whole number, put 1 underneath it and flip. Ex: 7=7/1, reciprocal=1/7.

Pre CALCULUS
What happens when you subtract x from both sides? It doesn't work. Plug in any number to see why. If x=1, then x+5=6. X always has to equal x and nothing else, so there are no solutions to this.
