3\left(2x-1\right)=4x
Multiply both sides of the equation by 12, the least common multiple of 4,3.
6x-3=4x
Use the distributive property to multiply 3 by 2x-1.
6x-3-4x=0
Subtract 4x from both sides.
2x-3=0
Combine 6x and -4x to get 2x.
2x=3
Add 3 to both sides. Anything plus zero gives itself.
x=\frac{3}{2}
Divide both sides by 2.
