First you multiply both sides by 3 so then it looks like:

3/6 - (3x)/2 = x-5

Then you put anything with variables on one side by adding (3x)/2 and 5 to both sides.

5.5 = x + (3x)/2

5.5 = 2.5 x

Now divide both sides by 2.5 to get the x by itself.

2.2 = x

Voila!

I would have stayed in fractions. When you get to college the professors there will want the exactness of fractions.

3/6 - 3X/2 = X - 5

3/6 = 1/2 and 5 = 10/2

1/2 - 3X/2 = X - 10/2

11/2 -3X/2 = X

11 - 3X = 2X

11 = 5X

X = 11/5
=========( which is, of course, 2.2 ) You will find fraction skills necessary in college algebra and calculus also. Some college math professors will not accept decimal answers, though in other college courses, science courses, they are perfectly five.
