Answer:
![x=-4](https://tex.z-dn.net/?f=x%3D-4)
Step-by-step explanation:
So we have the equation:
![3(2x+2)=18+4(x-5)](https://tex.z-dn.net/?f=3%282x%2B2%29%3D18%2B4%28x-5%29)
Distribute the left and the right:
![3(2x)+3(2)=18+4(x)+4(-5)](https://tex.z-dn.net/?f=3%282x%29%2B3%282%29%3D18%2B4%28x%29%2B4%28-5%29)
Simplify:
![6x+6=18+4x-20](https://tex.z-dn.net/?f=6x%2B6%3D18%2B4x-20)
Combine on the right:
![6x+6=4x-2](https://tex.z-dn.net/?f=6x%2B6%3D4x-2)
Subtract 4x from both sides. The right cancels:
![(6x+6)-4x=(4x-2)-4x\\2x+6=-2](https://tex.z-dn.net/?f=%286x%2B6%29-4x%3D%284x-2%29-4x%5C%5C2x%2B6%3D-2)
Subtract 6 from both sides. The left cancels:
![(2x+6)-6=(-2)-6\\2x=-8](https://tex.z-dn.net/?f=%282x%2B6%29-6%3D%28-2%29-6%5C%5C2x%3D-8)
Divide both sides by 2:
![(2x)/2=(-8)/2\\x=-4](https://tex.z-dn.net/?f=%282x%29%2F2%3D%28-8%29%2F2%5C%5Cx%3D-4)
Thus, the value of x is -4.
