We want to find the solution for the following equation
[tex]3y-8=25[/tex]If we perform the same operation on both sides of the equation, we're going to keep the equality.
To solve this problem, first we're going to add 8 to both sides.
[tex]\begin{gathered} 3y-8+8=25+8 \\ 3y=33 \end{gathered}[/tex]Now, if we divide both sides by 3 we're going to get the answer.
[tex]\begin{gathered} \frac{3y}{3}=\frac{33}{3} \\ y=11 \end{gathered}[/tex]
