2x-3\left(2x+1\right)=6\times 9+12-6x-x
Multiply both sides of the equation by 2.
2x-6x-3=6\times 9+12-6x-x
Use the distributive property to multiply -3 by 2x+1.
-4x-3=6\times 9+12-6x-x
Combine 2x and -6x to get -4x.
-4x-3=54+12-6x-x
Multiply 6 and 9 to get 54.
-4x-3=66-6x-x
Add 54 and 12 to get 66.
-4x-3+6x=66-x
Add 6x to both sides.
2x-3=66-x
Combine -4x and 6x to get 2x.
2x-3+x=66
Add x to both sides.
3x-3=66
Combine 2x and x to get 3x.
3x=66+3
Add 3 to both sides.
3x=69
Add 66 and 3 to get 69.
x=\frac{69}{3}
Divide both sides by 3.
x=23
Divide 69 by 3 to get 23.
