x = (5 +- sqrt(551)i)/48

Explanation:

First, add a 1 as a denominator for 8x:

5/3 - 2/x = (8x)/1

Then, find the GCF (Greatest Common Denominator), which in this case is 3x.

(5x)/(3x) - 6/(3x) = (24x^2)/(3x)

Next, since there is an equal sign, we can just eliminate the 3x from the denominator and have a simple equation:

5x - 6 = 24x^2

Put them all on 1 side.

24x^2 - 5x + 6 = 0

Do the quadratic formula:

x = -b +- (sqrt(b^2-4ac))/(2a)

x = 5 +- (sqrt(25 - 4(24)(6)))/48

Solve for x:

x = (5 +- sqrt(551)i)/48
