6\left(5\times \frac{5}{6}-6-3\right)-54\times 9=36x+36+0.3x
Multiply both sides of the equation by 6.
6\left(\frac{5\times 5}{6}-6-3\right)-54\times 9=36x+36+0.3x
Express 5\times \frac{5}{6} as a single fraction.
6\left(\frac{25}{6}-6-3\right)-54\times 9=36x+36+0.3x
Multiply 5 and 5 to get 25.
6\left(\frac{25}{6}-\frac{36}{6}-3\right)-54\times 9=36x+36+0.3x
Convert 6 to fraction \frac{36}{6}.
6\left(\frac{25-36}{6}-3\right)-54\times 9=36x+36+0.3x
Since \frac{25}{6} and \frac{36}{6} have the same denominator, subtract them by subtracting their numerators.
6\left(-\frac{11}{6}-3\right)-54\times 9=36x+36+0.3x
Subtract 36 from 25 to get -11.
6\left(-\frac{11}{6}-\frac{18}{6}\right)-54\times 9=36x+36+0.3x
Convert 3 to fraction \frac{18}{6}.
6\times \frac{-11-18}{6}-54\times 9=36x+36+0.3x
Since -\frac{11}{6} and \frac{18}{6} have the same denominator, subtract them by subtracting their numerators.
6\left(-\frac{29}{6}\right)-54\times 9=36x+36+0.3x
Subtract 18 from -11 to get -29.
-29-54\times 9=36x+36+0.3x
Cancel out 6 and 6.
-29-486=36x+36+0.3x
Multiply 54 and 9 to get 486.
-515=36x+36+0.3x
Subtract 486 from -29 to get -515.
-515=36.3x+36
Combine 36x and 0.3x to get 36.3x.
36.3x+36=-515
Swap sides so that all variable terms are on the left hand side.
36.3x=-515-36
Subtract 36 from both sides.
36.3x=-551
Subtract 36 from -515 to get -551.
x=\frac{-551}{36.3}
Divide both sides by 36.3.
x=\frac{-5510}{363}
Expand \frac{-551}{36.3} by multiplying both numerator and the denominator by 10.
x=-\frac{5510}{363}
Fraction \frac{-5510}{363} can be rewritten as -\frac{5510}{363} by extracting the negative sign.
