6\left(x-1\right)+4\left(x-2\right)=3\left(x-3\right)
Multiply both sides of the equation by 12, the least common multiple of 2,3,4.
6x-6+4\left(x-2\right)=3\left(x-3\right)
Use the distributive property to multiply 6 by x-1.
6x-6+4x-8=3\left(x-3\right)
Use the distributive property to multiply 4 by x-2.
10x-6-8=3\left(x-3\right)
Combine 6x and 4x to get 10x.
10x-14=3\left(x-3\right)
Subtract 8 from -6 to get -14.
10x-14=3x-9
Use the distributive property to multiply 3 by x-3.
10x-14-3x=-9
Subtract 3x from both sides.
7x-14=-9
Combine 10x and -3x to get 7x.
7x=-9+14
Add 14 to both sides.
7x=5
Add -9 and 14 to get 5.
x=\frac{5}{7}
Divide both sides by 7.
