Answer 2

$\large\displaystyle\begin{gathered}\sf 3x+2=2x+5 \end{gathered}$

$\large\displaystyle\begin{gathered}\sf 3x+2-\blue{2x}=2x+5-\blue{2x} \to \ Restar \ 2x \ de \ ambos \ lados. \end{gathered}$

$\large\displaystyle\begin{gathered}\sf x+2=5 \end{gathered}$

$\large\displaystyle\begin{gathered}\sf x+2-\blue{2}=5-\blue{2} \ \to \ \ Restar \ 2 \ de \ ambos \ lados. \end{gathered}$

$\large\displaystyle\begin{gathered}\sf \red{x=3 \ \Rightarrow \ \ Respuesta} \end{gathered}$
