Answer:
![\frac{13}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D)
Step-by-step explanation:
We have that:
![a=\frac{9}{2} \\b=2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B9%7D%7B2%7D%20%5C%5Cb%3D2)
Now we can find a+b
![\frac{9}{2}+2=\frac{9+4}{2}=\frac{13}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B2%7D%2B2%3D%5Cfrac%7B9%2B4%7D%7B2%7D%3D%5Cfrac%7B13%7D%7B2%7D)

Hope this helps!
9(2x-1)=3(x+2)+3x
18x-9=3x+6+3x
18x-9=6x+6
18x-6x=6+9
12x=15
x=15/12
x=5/4
Imma need more information on this?
