Given the equation,
[tex]\chi+2\chi+8=x[/tex]Using hands-on equation kit,
[tex]\begin{gathered} \text{Where,} \\ \chi=-2 \\ x=2 \end{gathered}[/tex]Substitute your values for the variables in the equation,
[tex]\begin{gathered} -2+2(-2)+8=2 \\ -2+(-4)+8=2 \\ -2-4+8=2 \\ -6+8=2 \\ 2=2 \end{gathered}[/tex]Hence,
[tex]\begin{gathered} \chi=-2\text{ and} \\ x=2\text{ } \\ \text{Check is 2=2} \end{gathered}[/tex]The answers have been deduced above.
