300\left(-\frac{6\times 3+2}{3}\right)x+1800=3\times 75
Multiply both sides of the equation by 300, the least common multiple of 3,100.
300\left(-\frac{18+2}{3}\right)x+1800=3\times 75
Multiply 6 and 3 to get 18.
300\left(-\frac{20}{3}\right)x+1800=3\times 75
Add 18 and 2 to get 20.
\frac{300\left(-20\right)}{3}x+1800=3\times 75
Express 300\left(-\frac{20}{3}\right) as a single fraction.
\frac{-6000}{3}x+1800=3\times 75
Multiply 300 and -20 to get -6000.
-2000x+1800=3\times 75
Divide -6000 by 3 to get -2000.
-2000x+1800=225
Multiply 3 and 75 to get 225.
-2000x=225-1800
Subtract 1800 from both sides.
-2000x=-1575
Subtract 1800 from 225 to get -1575.
x=\frac{-1575}{-2000}
Divide both sides by -2000.
x=\frac{63}{80}
Reduce the fraction \frac{-1575}{-2000} to lowest terms by extracting and canceling out -25.
