3\times 2\left(3x-4\right)=5\left(-9+15x\right)
Multiply both sides of the equation by 15, the least common multiple of 5,3.
6\left(3x-4\right)=5\left(-9+15x\right)
Multiply 3 and 2 to get 6.
18x-24=5\left(-9+15x\right)
Use the distributive property to multiply 6 by 3x-4.
18x-24=-45+75x
Use the distributive property to multiply 5 by -9+15x.
18x-24-75x=-45
Subtract 75x from both sides.
-57x-24=-45
Combine 18x and -75x to get -57x.
-57x=-45+24
Add 24 to both sides.
-57x=-21
Add -45 and 24 to get -21.
x=\frac{-21}{-57}
Divide both sides by -57.
x=\frac{7}{19}
Reduce the fraction \frac{-21}{-57} to lowest terms by extracting and canceling out -3.
