6x+9-4\left(x-5\right)=23
Use the distributive property to multiply 3 by 2x+3.
6x+9-4x+20=23
Use the distributive property to multiply -4 by x-5.
2x+9+20=23
Combine 6x and -4x to get 2x.
2x+29=23
Add 9 and 20 to get 29.
2x=23-29
Subtract 29 from both sides.
2x=-6
Subtract 29 from 23 to get -6.
x=\frac{-6}{2}
Divide both sides by 2.
x=-3
Divide -6 by 2 to get -3.
