Question 796792
Assuming the problem is
{{{((X+16))/x}}} = 8
Solve for x
multiply both sides by x
x + 16 = 8x
Subtract x from both sides
16 = 8x - x
16 = 7x
divide both sides by 7
x = {{{16/7}}}
:
However if the problem is
x + {{{16/x}}} = 8
multiply both sides by x and you have
x^2 + 16 = 8x
Arrange as a quadratic equation
x^2 - 8x = 16 = 0
factors to 
(x-4)(x-4) = 0
x = 4

The abundant use of brackets is very helpful in defining these problems. (They're free!)
