500-\frac{4}{3}\times 100000x=0
Calculate 10 to the power of 5 and get 100000.
500-\frac{4\times 100000}{3}x=0
Express \frac{4}{3}\times 100000 as a single fraction.
500-\frac{400000}{3}x=0
Multiply 4 and 100000 to get 400000.
-\frac{400000}{3}x=-500
Subtract 500 from both sides. Anything subtracted from zero gives its negation.
x=-500\left(-\frac{3}{400000}\right)
Multiply both sides by -\frac{3}{400000}, the reciprocal of -\frac{400000}{3}.
x=\frac{-500\left(-3\right)}{400000}
Express -500\left(-\frac{3}{400000}\right) as a single fraction.
x=\frac{1500}{400000}
Multiply -500 and -3 to get 1500.
x=\frac{3}{800}
Reduce the fraction \frac{1500}{400000} to lowest terms by extracting and canceling out 500.
