4/16-Solving Simple Eguatons

Lesson: Balance is the key to solving equations. 

y + 12 = -27   "The goal is to get the variable by itself."

                        To do that you must subtact 12 from each number.(Not including the varilable) You end up with a problem looking like this: y = 39. I got that by subracting 12 from each number. Then after you do that you bring the y down and the = sign and the other number and you get the answer y=39. I'll show you.

1. y + 12 = -27

2. 12-12=0

3.-27-12=39

you end up with this:y=39 that is the answer.

Hears a nother.

1. x + 6 =24

2. 6-6=0

3. 24-6=18

you end up with this: x=18
