20\left(2x-2\right)-360=12\left(4x-5\right)-15\left(x+3\right)
Multiply both sides of the equation by 60, the least common multiple of 3,5,4.
40x-40-360=12\left(4x-5\right)-15\left(x+3\right)
Use the distributive property to multiply 20 by 2x-2.
40x-400=12\left(4x-5\right)-15\left(x+3\right)
Subtract 360 from -40 to get -400.
40x-400=48x-60-15\left(x+3\right)
Use the distributive property to multiply 12 by 4x-5.
40x-400=48x-60-15x-45
Use the distributive property to multiply -15 by x+3.
40x-400=33x-60-45
Combine 48x and -15x to get 33x.
40x-400=33x-105
Subtract 45 from -60 to get -105.
40x-400-33x=-105
Subtract 33x from both sides.
7x-400=-105
Combine 40x and -33x to get 7x.
7x=-105+400
Add 400 to both sides.
7x=295
Add -105 and 400 to get 295.
x=\frac{295}{7}
Divide both sides by 7.
