-2/(x-5) = 4/(x+2) (from this step you have to cross multiply)
-2(x+2) = 4(x-5) (use the distributive property)
-2x - 4 = 4x - 20 (add like terms)
-6x = -16 (divide)
x = 8/3 (answer)

(4/9) x = That's not an equation. If there were a number after the 'equals' sign, then we could calculate the value of 'x'. But as it is, there's no question there, so there's nothing to solve.
the fraction is percent over 100 and fraction over the whole. Whatever number is missing you multiply across in an X with the end being the empty space.
To solve for x, we'd have to know what this expression equals.
x=12
you are saying 1.5 is equal to n over and 1.5 is equal to 1 over 6 first of all 1.5 is not euqal to one over six. but...if 1.5 = (n/3) then n=4.5
x means what ever the missing number is. if it was x over 7, you would have to solve for x.

c equals b over 8
Is it 15 over 40?
It equals 2 over 8.
This is an inequality equation in the form of: ii < xxii/viii which is the same as 2 < 22/8
