4\left(2x-1\right)=3\left(x+2\right)-12
Multiply both sides of the equation by 12, the least common multiple of 3,4.
8x-4=3\left(x+2\right)-12
Use the distributive property to multiply 4 by 2x-1.
8x-4=3x+6-12
Use the distributive property to multiply 3 by x+2.
8x-4=3x-6
Subtract 12 from 6 to get -6.
8x-4-3x=-6
Subtract 3x from both sides.
5x-4=-6
Combine 8x and -3x to get 5x.
5x=-6+4
Add 4 to both sides.
5x=-2
Add -6 and 4 to get -2.
x=\frac{-2}{5}
Divide both sides by 5.
x=-\frac{2}{5}
Fraction \frac{-2}{5} can be rewritten as -\frac{2}{5} by extracting the negative sign.
