4x+6-3\left(5x-4\right)=3\left(x-1\right)
Variable x cannot be equal to 1 since division by zero is not defined. Multiply both sides of the equation by 3\left(x-1\right), the least common multiple of 3\left(x-1\right),x-1.
4x+6-15x+12=3\left(x-1\right)
Use the distributive property to multiply -3 by 5x-4.
-11x+6+12=3\left(x-1\right)
Combine 4x and -15x to get -11x.
-11x+18=3\left(x-1\right)
Add 6 and 12 to get 18.
-11x+18=3x-3
Use the distributive property to multiply 3 by x-1.
-11x+18-3x=-3
Subtract 3x from both sides.
-14x+18=-3
Combine -11x and -3x to get -14x.
-14x=-3-18
Subtract 18 from both sides.
-14x=-21
Subtract 18 from -3 to get -21.
x=\frac{-21}{-14}
Divide both sides by -14.
x=\frac{3}{2}
Reduce the fraction \frac{-21}{-14} to lowest terms by extracting and canceling out -7.
