Use inverse operations to solve equations:


\begin{gathered} (x)/(-3)+11=23 \\ (x)/(-3)=23-11 \\ (x)/(-3)=12 \\ x=12\cdot-3 \\ x=-36 \end{gathered}

2.


\begin{gathered} 3+2v=11 \\ 2v=11-3 \\ v=(8)/(2)=4 \end{gathered}

3.


\begin{gathered} 16=(k)/(3)-11 \\ 16+11=(k)/(3) \\ 27=(k)/(3) \\ k=27\cdot3=81 \end{gathered}

4.


\begin{gathered} -6g-12=-60 \\ -6g=-60+12 \\ g=-(48)/(-6) \\ g=8 \end{gathered}

5.


\begin{gathered} \text{Combine like terms:} \\ 2a+5-5a+1 \\ (2a-5a)+(5+1) \end{gathered}

6.


\begin{gathered} m-4+3m-2 \\ (m+3m)-(4+2) \end{gathered}
