3\left(x-3\right)+4\left(x-1\right)=12x-48
Multiply both sides of the equation by 12, the least common multiple of 4,3.
3x-9+4\left(x-1\right)=12x-48
Use the distributive property to multiply 3 by x-3.
3x-9+4x-4=12x-48
Use the distributive property to multiply 4 by x-1.
7x-9-4=12x-48
Combine 3x and 4x to get 7x.
7x-13=12x-48
Subtract 4 from -9 to get -13.
7x-13-12x=-48
Subtract 12x from both sides.
-5x-13=-48
Combine 7x and -12x to get -5x.
-5x=-48+13
Add 13 to both sides.
-5x=-35
Add -48 and 13 to get -35.
x=\frac{-35}{-5}
Divide both sides by -5.
x=7
Divide -35 by -5 to get 7.
