-\frac{1}{2}\times 0.2\left(6x+1\right)=0.5x
Multiply both sides of the equation by -9.
-\frac{1}{2}\times \frac{1}{5}\left(6x+1\right)=0.5x
Convert decimal number 0.2 to fraction \frac{2}{10}. Reduce the fraction \frac{2}{10} to lowest terms by extracting and canceling out 2.
\frac{-1}{2\times 5}\left(6x+1\right)=0.5x
Multiply -\frac{1}{2} times \frac{1}{5} by multiplying numerator times numerator and denominator times denominator.
\frac{-1}{10}\left(6x+1\right)=0.5x
Do the multiplications in the fraction \frac{-1}{2\times 5}.
-\frac{1}{10}\left(6x+1\right)=0.5x
Fraction \frac{-1}{10} can be rewritten as -\frac{1}{10} by extracting the negative sign.
-\frac{1}{10}\times 6x-\frac{1}{10}=0.5x
Use the distributive property to multiply -\frac{1}{10} by 6x+1.
\frac{-6}{10}x-\frac{1}{10}=0.5x
Express -\frac{1}{10}\times 6 as a single fraction.
-\frac{3}{5}x-\frac{1}{10}=0.5x
Reduce the fraction \frac{-6}{10} to lowest terms by extracting and canceling out 2.
-\frac{3}{5}x-\frac{1}{10}-0.5x=0
Subtract 0.5x from both sides.
-\frac{11}{10}x-\frac{1}{10}=0
Combine -\frac{3}{5}x and -0.5x to get -\frac{11}{10}x.
-\frac{11}{10}x=\frac{1}{10}
Add \frac{1}{10} to both sides. Anything plus zero gives itself.
x=\frac{1}{10}\left(-\frac{10}{11}\right)
Multiply both sides by -\frac{10}{11}, the reciprocal of -\frac{11}{10}.
x=\frac{1\left(-10\right)}{10\times 11}
Multiply \frac{1}{10} times -\frac{10}{11} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-10}{110}
Do the multiplications in the fraction \frac{1\left(-10\right)}{10\times 11}.
x=-\frac{1}{11}
Reduce the fraction \frac{-10}{110} to lowest terms by extracting and canceling out 10.
