20\left(x-4\right)+15\left(2x-4\right)=12\times 5x-10\left(5x-6\right)
Multiply both sides of the equation by 120, the least common multiple of 6,8,10,12.
20x-80+15\left(2x-4\right)=12\times 5x-10\left(5x-6\right)
Use the distributive property to multiply 20 by x-4.
20x-80+30x-60=12\times 5x-10\left(5x-6\right)
Use the distributive property to multiply 15 by 2x-4.
50x-80-60=12\times 5x-10\left(5x-6\right)
Combine 20x and 30x to get 50x.
50x-140=12\times 5x-10\left(5x-6\right)
Subtract 60 from -80 to get -140.
50x-140=60x-10\left(5x-6\right)
Multiply 12 and 5 to get 60.
50x-140=60x-50x+60
Use the distributive property to multiply -10 by 5x-6.
50x-140=10x+60
Combine 60x and -50x to get 10x.
50x-140-10x=60
Subtract 10x from both sides.
40x-140=60
Combine 50x and -10x to get 40x.
40x=60+140
Add 140 to both sides.
40x=200
Add 60 and 140 to get 200.
x=\frac{200}{40}
Divide both sides by 40.
x=5
Divide 200 by 40 to get 5.
