Answer:
x= -12
Step-by-step explanation:
3(x+7)+6= -9
3x+21+6= -9
subtract 6 from both sides that gives you your equation that you can work with.
3x+21= -15
then subtract 21 from both sides that gives you
3x/3 = -36/3
the 3 cancels out and leaves you with -36 divided by 3
your answer is -12

[tex]\fbox {x=-12}[/tex]
[tex]\text {Your 1st Step is to Simplify the Equation}[/tex]
[tex]\text {(3)(x)+(3)(7)+6=-9 (Distribute)}[/tex]
[tex]\text {3x+21+6=-9}[/tex]
[tex]\text {(3x)+(21+6)=-9 (Combine Like Terms)}[/tex]
[tex]\text {3x+27=-9}[/tex]
[tex]\text {Your 2nd Step is to Subtract 27}[/tex]
[tex]\text {3x+27-27=-9-27}[/tex]
[tex]\text {3x=-36}[/tex]
[tex]\text {Your 3rd/Final Step is to Divide 3}[/tex]
[tex]\text {3x/3=-36/3}[/tex]
[tex]\fbox {x=-12}[/tex]
