Certainly! Let's complete the proof by providing the necessary statements and reasons.
Given: [tex]\( 6a - 2 = 3(a + 1) + 1 \)[/tex]
Prove: [tex]\( a = 2 \)[/tex]
\begin{tabular}{|l|l|}
\hline
\multicolumn{1}{|c|}{Statements} & \multicolumn{1}{c|}{Reasons} \\
\hline
[tex]\( 6a - 2 = 3(a + 1) + 1 \)[/tex] & Given \\
\hline
[tex]\( 6a - 2 = 3a + 3 + 1 \)[/tex] & Distributive property \\
\hline
[tex]\( 6a - 2 = 3a + 4 \)[/tex] & Combine like terms on the right side \\
\hline
[tex]\( 6a - 3a - 2 = 4 \)[/tex] & Subtract [tex]\( 3a \)[/tex] from both sides \\
\hline
[tex]\( 3a - 2 = 4 \)[/tex] & Simplify \\
\hline
[tex]\( 3a - 2 + 2 = 4 + 2 \)[/tex] & Add 2 to both sides \\
\hline
[tex]\( 3a = 6 \)[/tex] & Simplify \\
\hline
[tex]\( a = 2 \)[/tex] & Divide both sides by 3 \\
\hline
\end{tabular}
Thus, we have proven that [tex]\( a = 2 \)[/tex].
