6\left(2x-3\right)+5\times 3\left(x-1\right)=2\times 2\left(x-3\right)+30x
Multiply both sides of the equation by 30, the least common multiple of 5,6,15.
12x-18+5\times 3\left(x-1\right)=2\times 2\left(x-3\right)+30x
Use the distributive property to multiply 6 by 2x-3.
12x-18+15\left(x-1\right)=2\times 2\left(x-3\right)+30x
Multiply 5 and 3 to get 15.
12x-18+15x-15=2\times 2\left(x-3\right)+30x
Use the distributive property to multiply 15 by x-1.
27x-18-15=2\times 2\left(x-3\right)+30x
Combine 12x and 15x to get 27x.
27x-33=2\times 2\left(x-3\right)+30x
Subtract 15 from -18 to get -33.
27x-33=4\left(x-3\right)+30x
Multiply 2 and 2 to get 4.
27x-33=4x-12+30x
Use the distributive property to multiply 4 by x-3.
27x-33=34x-12
Combine 4x and 30x to get 34x.
27x-33-34x=-12
Subtract 34x from both sides.
-7x-33=-12
Combine 27x and -34x to get -7x.
-7x=-12+33
Add 33 to both sides.
-7x=21
Add -12 and 33 to get 21.
x=\frac{21}{-7}
Divide both sides by -7.
x=-3
Divide 21 by -7 to get -3.
