2\left(2x-3\right)-3\left(3x+4\right)=4
Multiply both sides of the equation by 6, the least common multiple of 3,2.
4x-6-3\left(3x+4\right)=4
Use the distributive property to multiply 2 by 2x-3.
4x-6-9x-12=4
Use the distributive property to multiply -3 by 3x+4.
-5x-6-12=4
Combine 4x and -9x to get -5x.
-5x-18=4
Subtract 12 from -6 to get -18.
-5x=4+18
Add 18 to both sides.
-5x=22
Add 4 and 18 to get 22.
x=\frac{22}{-5}
Divide both sides by -5.
x=-\frac{22}{5}
Fraction \frac{22}{-5} can be rewritten as -\frac{22}{5} by extracting the negative sign.
