Question
How do I solve this equation?
5x/2 + 3/4 = 9/3 the division symbols are fractions.

Answer
The best way I've found to approach problems with fraction in them
is to get rid of the fractions.

The easiest fraction to get rid of is 9/3, for 9/3 = 3.

We then have 5x/2 + 3/4 = 3.

Multiplying each term by 4 gives 4*5x/2 + 3 = 4*3.
Since 4*5/2 = 2*2*5/2 = 2*5 = 10 or 4*5/2 = 20/2 = 10, and
4*3 = 12, that is the same as
10x + 3 = 12.

Subtracting 3 from both sides gives 10x = 9.

Now that the x terms is on one side and the constant on the other,
we can divide by the multiple of x.  That is, divide both sides by 10.
That gives x = 9/10.

Putting that back into 5x/2 + 3/4 = 3 gives ...
Well, the first term 5x/2, is really (5/2)x = (5/2)(9/10).
This can be rewritten as (5/2)(9/(5*2)) = (1/2)(9/2) = 9/4.

The left side is then 9/4 + 3/4 = 12/4 = 3.
Multiplying by 3/3 gives 9/3, and that's what's on the right.
