Hello!
First, let's write the problem.
[tex]4+3s-9s=22[/tex]
Add like terms,
[tex]4-6s=22[/tex]
Subtract 4 from both sides.
[tex]4-6s-4=22-4[/tex]
[tex]-6s=18[/tex]
Divide both sides by -6.
[tex]\frac{-6s}{-6}=\frac{18}{-6}[/tex]
Our final answer would be,
[tex]s=-3[/tex]
You can feel free to let me know if you have any questions regarding this!
Thanks!
