<u>Answer:</u>
x = -3/7
<u>Step-by-step explanation:</u>
We are given the following equation for which we have to solve for x:
![3(3x - 1) + 2(3 - x) = 0](https://tex.z-dn.net/?f=3%283x%20-%201%29%20%2B%202%283%20-%20x%29%20%3D%200)
So we will start by expanding the equation by multiplying the common factor with the brackets to get:
![9x-3+6-2x=0](https://tex.z-dn.net/?f=9x-3%2B6-2x%3D0)
Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:
![9x-2x=3-6\\\\7x=-3\\\\x=-\frac{3}{7}](https://tex.z-dn.net/?f=9x-2x%3D3-6%5C%5C%5C%5C7x%3D-3%5C%5C%5C%5Cx%3D-%5Cfrac%7B3%7D%7B7%7D)
Therefore, x = -3/7.
