40\times 4\left(x-2\right)+15\left(3x+1\right)=24\times 3\left(6x-5\right)-1080
Multiply both sides of the equation by 120, the least common multiple of 3,8,5.
160\left(x-2\right)+15\left(3x+1\right)=24\times 3\left(6x-5\right)-1080
Multiply 40 and 4 to get 160.
160x-320+15\left(3x+1\right)=24\times 3\left(6x-5\right)-1080
Use the distributive property to multiply 160 by x-2.
160x-320+45x+15=24\times 3\left(6x-5\right)-1080
Use the distributive property to multiply 15 by 3x+1.
205x-320+15=24\times 3\left(6x-5\right)-1080
Combine 160x and 45x to get 205x.
205x-305=24\times 3\left(6x-5\right)-1080
Add -320 and 15 to get -305.
205x-305=72\left(6x-5\right)-1080
Multiply 24 and 3 to get 72.
205x-305=432x-360-1080
Use the distributive property to multiply 72 by 6x-5.
205x-305=432x-1440
Subtract 1080 from -360 to get -1440.
205x-305-432x=-1440
Subtract 432x from both sides.
-227x-305=-1440
Combine 205x and -432x to get -227x.
-227x=-1440+305
Add 305 to both sides.
-227x=-1135
Add -1440 and 305 to get -1135.
x=\frac{-1135}{-227}
Divide both sides by -227.
x=5
Divide -1135 by -227 to get 5.
