-\frac{2}{3}x+\frac{5}{3}+\frac{2}{5}x=-6
Add \frac{2}{5}x to both sides.
-\frac{4}{15}x+\frac{5}{3}=-6
Combine -\frac{2}{3}x and \frac{2}{5}x to get -\frac{4}{15}x.
-\frac{4}{15}x=-6-\frac{5}{3}
Subtract \frac{5}{3} from both sides.
-\frac{4}{15}x=-\frac{18}{3}-\frac{5}{3}
Convert -6 to fraction -\frac{18}{3}.
-\frac{4}{15}x=\frac{-18-5}{3}
Since -\frac{18}{3} and \frac{5}{3} have the same denominator, subtract them by subtracting their numerators.
-\frac{4}{15}x=-\frac{23}{3}
Subtract 5 from -18 to get -23.
x=-\frac{23}{3}\left(-\frac{15}{4}\right)
Multiply both sides by -\frac{15}{4}, the reciprocal of -\frac{4}{15}.
x=\frac{-23\left(-15\right)}{3\times 4}
Multiply -\frac{23}{3} times -\frac{15}{4} by multiplying numerator times numerator and denominator times denominator.
x=\frac{345}{12}
Do the multiplications in the fraction \frac{-23\left(-15\right)}{3\times 4}.
x=\frac{115}{4}
Reduce the fraction \frac{345}{12} to lowest terms by extracting and canceling out 3.
