2\times 2x+3\left(8-x\right)=6\left(-\frac{4}{3}\right)^{3}+6
Multiply both sides of the equation by 6, the least common multiple of 3,6.
4x+3\left(8-x\right)=6\left(-\frac{4}{3}\right)^{3}+6
Multiply 2 and 2 to get 4.
4x+24-3x=6\left(-\frac{4}{3}\right)^{3}+6
Use the distributive property to multiply 3 by 8-x.
x+24=6\left(-\frac{4}{3}\right)^{3}+6
Combine 4x and -3x to get x.
x+24=6\left(-\frac{64}{27}\right)+6
Calculate -\frac{4}{3} to the power of 3 and get -\frac{64}{27}.
x+24=\frac{6\left(-64\right)}{27}+6
Express 6\left(-\frac{64}{27}\right) as a single fraction.
x+24=\frac{-384}{27}+6
Multiply 6 and -64 to get -384.
x+24=-\frac{128}{9}+6
Reduce the fraction \frac{-384}{27} to lowest terms by extracting and canceling out 3.
x+24=-\frac{128}{9}+\frac{54}{9}
Convert 6 to fraction \frac{54}{9}.
x+24=\frac{-128+54}{9}
Since -\frac{128}{9} and \frac{54}{9} have the same denominator, add them by adding their numerators.
x+24=-\frac{74}{9}
Add -128 and 54 to get -74.
x=-\frac{74}{9}-24
Subtract 24 from both sides.
x=-\frac{74}{9}-\frac{216}{9}
Convert 24 to fraction \frac{216}{9}.
x=\frac{-74-216}{9}
Since -\frac{74}{9} and \frac{216}{9} have the same denominator, subtract them by subtracting their numerators.
x=-\frac{290}{9}
Subtract 216 from -74 to get -290.
