Answer:
[tex]\huge\mathrm{\displaystyle-\frac{7}{2} }[/tex]
Explanation:
Hi there, I hope you are having a nice day! :)
First of all, let's move all the numbers to the right:
[tex]\longmapsto\sf{6x+9=-12[/tex]
[tex]\longmapsto\sf{6x=-12-9[/tex]
[tex]\longmapsto\sf{6x=-21[/tex]
Divide both sides by 6:
[tex]\longmapsto\sf{x=\displaystyle-\frac{21}{6}[/tex]
Simplify:
[tex]\longmapsto\sf{x=\displaystyle-\frac{7}{2}[/tex] (Answer)
Hope you find it helpful.
Feel free to ask if you have any doubts.
