27\times \left(\frac{-2}{3}\right)^{-3}=4x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 27x, the least common multiple of x,27.
27\left(-\frac{2}{3}\right)^{-3}=4x
Fraction \frac{-2}{3} can be rewritten as -\frac{2}{3} by extracting the negative sign.
27\left(-\frac{27}{8}\right)=4x
Calculate -\frac{2}{3} to the power of -3 and get -\frac{27}{8}.
-\frac{729}{8}=4x
Multiply 27 and -\frac{27}{8} to get -\frac{729}{8}.
4x=-\frac{729}{8}
Swap sides so that all variable terms are on the left hand side.
x=\frac{-\frac{729}{8}}{4}
Divide both sides by 4.
x=\frac{-729}{8\times 4}
Express \frac{-\frac{729}{8}}{4} as a single fraction.
x=\frac{-729}{32}
Multiply 8 and 4 to get 32.
x=-\frac{729}{32}
Fraction \frac{-729}{32} can be rewritten as -\frac{729}{32} by extracting the negative sign.
