6\left(x-\frac{5}{3}\left(x+4\right)\right)=5\left(x-3\right)-10\left(x+2\right)
Multiply both sides of the equation by 15, the least common multiple of 5,3.
6\left(x-\frac{5}{3}x-\frac{5}{3}\times 4\right)=5\left(x-3\right)-10\left(x+2\right)
Use the distributive property to multiply -\frac{5}{3} by x+4.
6\left(x-\frac{5}{3}x+\frac{-5\times 4}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Express -\frac{5}{3}\times 4 as a single fraction.
6\left(x-\frac{5}{3}x+\frac{-20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Multiply -5 and 4 to get -20.
6\left(x-\frac{5}{3}x-\frac{20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Fraction \frac{-20}{3} can be rewritten as -\frac{20}{3} by extracting the negative sign.
6\left(-\frac{2}{3}x-\frac{20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Combine x and -\frac{5}{3}x to get -\frac{2}{3}x.
6\left(-\frac{2}{3}\right)x+6\left(-\frac{20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Use the distributive property to multiply 6 by -\frac{2}{3}x-\frac{20}{3}.
\frac{6\left(-2\right)}{3}x+6\left(-\frac{20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Express 6\left(-\frac{2}{3}\right) as a single fraction.
\frac{-12}{3}x+6\left(-\frac{20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Multiply 6 and -2 to get -12.
-4x+6\left(-\frac{20}{3}\right)=5\left(x-3\right)-10\left(x+2\right)
Divide -12 by 3 to get -4.
-4x+\frac{6\left(-20\right)}{3}=5\left(x-3\right)-10\left(x+2\right)
Express 6\left(-\frac{20}{3}\right) as a single fraction.
-4x+\frac{-120}{3}=5\left(x-3\right)-10\left(x+2\right)
Multiply 6 and -20 to get -120.
-4x-40=5\left(x-3\right)-10\left(x+2\right)
Divide -120 by 3 to get -40.
-4x-40=5x-15-10\left(x+2\right)
Use the distributive property to multiply 5 by x-3.
-4x-40=5x-15-10x-20
Use the distributive property to multiply -10 by x+2.
-4x-40=-5x-15-20
Combine 5x and -10x to get -5x.
-4x-40=-5x-35
Subtract 20 from -15 to get -35.
-4x-40+5x=-35
Add 5x to both sides.
x-40=-35
Combine -4x and 5x to get x.
x=-35+40
Add 40 to both sides.
x=5
Add -35 and 40 to get 5.
