Number 22 I need the answer and how to put it the correct way

Question:
Solution:
Consider the following equation:
[tex]3x\text{ +2(x-1) = 9x+4}[/tex]applying the distributive property, we get:
[tex]3x\text{ +2x-2 = 9x+4}[/tex]now, putting the like terms together, we obtain:
[tex]3x\text{ +2x -9x = 4 +2}[/tex]this is equivalent to:
[tex]-4x\text{ = 6}[/tex]solving for x, we get:
[tex]x\text{ =- }\frac{6}{4}\text{ = -}\frac{3}{2}[/tex]we can conclude that the correct answer is:
[tex]x\text{ =-}\frac{3}{2}[/tex]
