10\times 2\left(x-1\right)-6\times 3\left(4x-1\right)=15\times 5\left(3x-2\right)-960
Multiply both sides of the equation by 30, the least common multiple of 3,5,2.
20\left(x-1\right)-6\times 3\left(4x-1\right)=15\times 5\left(3x-2\right)-960
Multiply 10 and 2 to get 20.
20x-20-6\times 3\left(4x-1\right)=15\times 5\left(3x-2\right)-960
Use the distributive property to multiply 20 by x-1.
20x-20-18\left(4x-1\right)=15\times 5\left(3x-2\right)-960
Multiply -6 and 3 to get -18.
20x-20-72x+18=15\times 5\left(3x-2\right)-960
Use the distributive property to multiply -18 by 4x-1.
-52x-20+18=15\times 5\left(3x-2\right)-960
Combine 20x and -72x to get -52x.
-52x-2=15\times 5\left(3x-2\right)-960
Add -20 and 18 to get -2.
-52x-2=75\left(3x-2\right)-960
Multiply 15 and 5 to get 75.
-52x-2=225x-150-960
Use the distributive property to multiply 75 by 3x-2.
-52x-2=225x-1110
Subtract 960 from -150 to get -1110.
-52x-2-225x=-1110
Subtract 225x from both sides.
-277x-2=-1110
Combine -52x and -225x to get -277x.
-277x=-1110+2
Add 2 to both sides.
-277x=-1108
Add -1110 and 2 to get -1108.
x=\frac{-1108}{-277}
Divide both sides by -277.
x=4
Divide -1108 by -277 to get 4.
