-\frac{1}{7}\times 6x-\frac{1}{7}\times 13=\frac{3}{5}\left(\frac{1}{3}-x\right)
Use the distributive property to multiply -\frac{1}{7} by 6x+13.
\frac{-6}{7}x-\frac{1}{7}\times 13=\frac{3}{5}\left(\frac{1}{3}-x\right)
Express -\frac{1}{7}\times 6 as a single fraction.
-\frac{6}{7}x-\frac{1}{7}\times 13=\frac{3}{5}\left(\frac{1}{3}-x\right)
Fraction \frac{-6}{7} can be rewritten as -\frac{6}{7} by extracting the negative sign.
-\frac{6}{7}x+\frac{-13}{7}=\frac{3}{5}\left(\frac{1}{3}-x\right)
Express -\frac{1}{7}\times 13 as a single fraction.
-\frac{6}{7}x-\frac{13}{7}=\frac{3}{5}\left(\frac{1}{3}-x\right)
Fraction \frac{-13}{7} can be rewritten as -\frac{13}{7} by extracting the negative sign.
-\frac{6}{7}x-\frac{13}{7}=\frac{3}{5}\times \frac{1}{3}+\frac{3}{5}\left(-1\right)x
Use the distributive property to multiply \frac{3}{5} by \frac{1}{3}-x.
-\frac{6}{7}x-\frac{13}{7}=\frac{3\times 1}{5\times 3}+\frac{3}{5}\left(-1\right)x
Multiply \frac{3}{5} times \frac{1}{3} by multiplying numerator times numerator and denominator times denominator.
-\frac{6}{7}x-\frac{13}{7}=\frac{1}{5}+\frac{3}{5}\left(-1\right)x
Cancel out 3 in both numerator and denominator.
-\frac{6}{7}x-\frac{13}{7}=\frac{1}{5}-\frac{3}{5}x
Multiply \frac{3}{5} and -1 to get -\frac{3}{5}.
-\frac{6}{7}x-\frac{13}{7}+\frac{3}{5}x=\frac{1}{5}
Add \frac{3}{5}x to both sides.
-\frac{9}{35}x-\frac{13}{7}=\frac{1}{5}
Combine -\frac{6}{7}x and \frac{3}{5}x to get -\frac{9}{35}x.
-\frac{9}{35}x=\frac{1}{5}+\frac{13}{7}
Add \frac{13}{7} to both sides.
-\frac{9}{35}x=\frac{7}{35}+\frac{65}{35}
Least common multiple of 5 and 7 is 35. Convert \frac{1}{5} and \frac{13}{7} to fractions with denominator 35.
-\frac{9}{35}x=\frac{7+65}{35}
Since \frac{7}{35} and \frac{65}{35} have the same denominator, add them by adding their numerators.
-\frac{9}{35}x=\frac{72}{35}
Add 7 and 65 to get 72.
x=\frac{72}{35}\left(-\frac{35}{9}\right)
Multiply both sides by -\frac{35}{9}, the reciprocal of -\frac{9}{35}.
x=\frac{72\left(-35\right)}{35\times 9}
Multiply \frac{72}{35} times -\frac{35}{9} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-2520}{315}
Do the multiplications in the fraction \frac{72\left(-35\right)}{35\times 9}.
x=-8
Divide -2520 by 315 to get -8.
