We can do the following steps to solve the equation.
Step 1: Add 26 from both sides.
[tex]\begin{gathered} -51+26=5y-26+26 \\ -25=5y \end{gathered}[/tex]Step 2: Divide by 5 from both sides.
[tex]\begin{gathered} \frac{-25}{5}=\frac{5y}{5} \\ -5=y \end{gathered}[/tex]AnswerThe solution of the equation is y = -5.
