Solution:
The equation is given below as
[tex]6x-2+6x=-2[/tex]Collect similar terms, we will have
[tex]\begin{gathered} 6x-2+6x=-2 \\ 6x+6x-2=-2 \end{gathered}[/tex]add 2 to both sides
[tex]\begin{gathered} 6x+6x-2=-2 \\ 12x-2+2=-2+2 \\ 12x=0 \\ \frac{12x}{12}=\frac{0}{12} \\ x=0 \end{gathered}[/tex]Hence,
The final answer is
[tex]\Rightarrow x=0[/tex]
