Answer :

[tex]\frac{9+t}{12}=-3[/tex]

12 is dividing on the left, then it will multiply on the right.

[tex]\begin{gathered} 9+t=(-3)\cdot12 \\ 9+t=-36 \end{gathered}[/tex]

9 is adding on the left, then it will subtract on the right

t = -36 - 9

t = -45

To check the answer, replace the value found into the original equation, as follows:

[tex]\frac{9-45}{12}=\frac{-36}{12}=-3[/tex]
