Look at it this way: if you have money, it's a positive number and if you owe money, it's a negative number. You owe $4, you owe $9..do you owe money or have money? That tells you your sign. How much?

.83 is read as 83 hundredths because it goes up to the hundredths place. If you don't know this, study place value. So you re-write it as 83/100 and then simplify to 5/6.

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.
