6\left(x-3\right)+4\left(6-x\right)=12+3\left(1+2x\right)
Multiply both sides of the equation by 12, the least common multiple of 2,3,4.
6x-18+4\left(6-x\right)=12+3\left(1+2x\right)
Use the distributive property to multiply 6 by x-3.
6x-18+24-4x=12+3\left(1+2x\right)
Use the distributive property to multiply 4 by 6-x.
6x+6-4x=12+3\left(1+2x\right)
Add -18 and 24 to get 6.
2x+6=12+3\left(1+2x\right)
Combine 6x and -4x to get 2x.
2x+6=12+3+6x
Use the distributive property to multiply 3 by 1+2x.
2x+6=15+6x
Add 12 and 3 to get 15.
2x+6-6x=15
Subtract 6x from both sides.
-4x+6=15
Combine 2x and -6x to get -4x.
-4x=15-6
Subtract 6 from both sides.
-4x=9
Subtract 6 from 15 to get 9.
x=\frac{9}{-4}
Divide both sides by -4.
x=-\frac{9}{4}
Fraction \frac{9}{-4} can be rewritten as -\frac{9}{4} by extracting the negative sign.
