Answer:
<em>X can equal 22.5 </em>
Step-by-step explanation:
I've set up the equation below:

With this equation, as any addition equation goes, we assume it to be like this:
A + B = C
so
C - A = B
that means,

The easiest thing to do is to make 2/3 have the same denominator as 8/9, we do this by...

So...

We now know that 5 over x equals 2 over nine. We can determine x by cross multiplying as follows:

So, x is 22.5, making the equation indeed solvable.

(-9+or- the square root of 45)/2
The simplified expression will be 16+5f because in the parentheses you add 4 and f, f has an invisible one to it so 1 plus 4 equals 5 and f, 16+5f is your expression, but the answer is 21f, expression is 16+5f and answer is 21f
