\frac{1}{10}x+\frac{1}{10}\times 51=-2\left(6-x\right)
Use the distributive property to multiply \frac{1}{10} by x+51.
\frac{1}{10}x+\frac{51}{10}=-2\left(6-x\right)
Multiply \frac{1}{10} and 51 to get \frac{51}{10}.
\frac{1}{10}x+\frac{51}{10}=-12+2x
Use the distributive property to multiply -2 by 6-x.
\frac{1}{10}x+\frac{51}{10}-2x=-12
Subtract 2x from both sides.
-\frac{19}{10}x+\frac{51}{10}=-12
Combine \frac{1}{10}x and -2x to get -\frac{19}{10}x.
-\frac{19}{10}x=-12-\frac{51}{10}
Subtract \frac{51}{10} from both sides.
-\frac{19}{10}x=-\frac{120}{10}-\frac{51}{10}
Convert -12 to fraction -\frac{120}{10}.
-\frac{19}{10}x=\frac{-120-51}{10}
Since -\frac{120}{10} and \frac{51}{10} have the same denominator, subtract them by subtracting their numerators.
-\frac{19}{10}x=-\frac{171}{10}
Subtract 51 from -120 to get -171.
x=-\frac{171}{10}\left(-\frac{10}{19}\right)
Multiply both sides by -\frac{10}{19}, the reciprocal of -\frac{19}{10}.
x=\frac{-171\left(-10\right)}{10\times 19}
Multiply -\frac{171}{10} times -\frac{10}{19} by multiplying numerator times numerator and denominator times denominator.
x=\frac{1710}{190}
Do the multiplications in the fraction \frac{-171\left(-10\right)}{10\times 19}.
x=9
Divide 1710 by 190 to get 9.
