The given equation is:
[tex]12+\frac{e}{5}=7[/tex]Step 1. Subtract 12 from both sides
[tex]\begin{gathered} 12-12+\frac{e}{5}=7-12 \\ \\ \frac{e}{5}=-5 \end{gathered}[/tex]Step 2. Multiply both sides by 5 and simplify:
[tex]\begin{gathered} \frac{e}{5}*5=-5*5 \\ e=-25 \end{gathered}[/tex]The answer is e=-25
