Answer:

[tex]x=-6[/tex]

Step-by-step explanation:

[tex]-13+22=-3(x+3)[/tex]

Switch sides:

[tex]-3\left(x+3\right)=-13+22[/tex]

Solve the right side:

[tex]-3\left(x+3\right)=9[/tex]

Divide both sides by -3:

[tex]\frac{-3\left(x+3\right)}{-3}=\frac{9}{-3}[/tex]

[tex]x+3=-3[/tex]

Subtract 3 from both sides:

[tex]x+3-3=-3-3[/tex]

[tex]x=-6[/tex]

Answer:

-6

Step-by-step explanation:

9=-3x-9  calculate 3x=-9-9. divide both sides 3x=-18
