10\left(2x-1\right)-2x-3\times 2\left(x+2\right)=20+15\left(x-1\right)
Multiply both sides of the equation by 30, the least common multiple of 3,15,10,2.
20x-10-2x-3\times 2\left(x+2\right)=20+15\left(x-1\right)
Use the distributive property to multiply 10 by 2x-1.
18x-10-3\times 2\left(x+2\right)=20+15\left(x-1\right)
Combine 20x and -2x to get 18x.
18x-10-6\left(x+2\right)=20+15\left(x-1\right)
Multiply -3 and 2 to get -6.
18x-10-6x-12=20+15\left(x-1\right)
Use the distributive property to multiply -6 by x+2.
12x-10-12=20+15\left(x-1\right)
Combine 18x and -6x to get 12x.
12x-22=20+15\left(x-1\right)
Subtract 12 from -10 to get -22.
12x-22=20+15x-15
Use the distributive property to multiply 15 by x-1.
12x-22=5+15x
Subtract 15 from 20 to get 5.
12x-22-15x=5
Subtract 15x from both sides.
-3x-22=5
Combine 12x and -15x to get -3x.
-3x=5+22
Add 22 to both sides.
-3x=27
Add 5 and 22 to get 27.
x=\frac{27}{-3}
Divide both sides by -3.
x=-9
Divide 27 by -3 to get -9.
