what dose x =

Well, if this one seems hard, start with this one:
x + 3 = 5
You solve it by taking 3 from each side:
x + 3 - 3 = 5 - 3
x = 5 - 3
x = 2
OK so far? Now, for the problem you give, the only new wrinkle is that you have a fraction. Start the same way:
x + 3 - 3 = 9/2 - 3
x = 9/2 - 3
Now, to subtract 9/2 from 3, get the common denominator. 3 = 6/2. So...
x = 9/2 - 6/2 = 3/2
x = 3/2 is your answer.
If the common denominator part is losing you, get a little help from the teacher.

Subtract 3 from each side, which means x = (9/2) - 3. Put your terms together and you are finished, and get (3/2), or 1.5.

x+3= 9/2
( 9/2 = 4.5)
So, x+3=4.5
Subtract 3 from both sides of equation.
X= 1.5 OR 3/2
