X = 15
Step-by-step explanation:
9x = -135
Divide by 9 on both sides
X = -15
It is -15 since 135 is negative

\huge\text{Hey there!}


\huge\boxed{\mathsf{9x = -135}}


\huge\boxed{\text{DIVIDE 9 to BOTH SIDES}}


\huge\boxed{\mathsf{(9x)/(9)= (-135)/(9)}}


\huge\boxed{\mathsf{\bullet \ CANCEL: (9)/(9)\ because\ it \ gives\ you\ 1}}


\huge\boxed{\bullet\ \mathsf{KEEP: (-135)/(9)\ because\ it\ helps\ solve \ for}}\\\huge\boxed{\mathsf{the\ x-value}}


\huge\boxed{\mathsf{x = (-135)/(9)}}\\\\\huge\boxed{\mathsf{(-135)/(9)= x}}}


\huge\boxed{Simplify \ it\uparrow}


\huge\boxed{\mathsf{x = \bf -15}}


\huge\boxed{\textsf{Therefore, your answer is: Option D. -15 }}\huge\checkmark
