\"\"\"\"

\

Given equation is \"\". \ \

\

\"\"         (Add 3 to each side) \ \

\

\"\"                      (Additive inverse property: \"\")

\

\"\"                            (Add: \"\")

\

\"\"          (Add 6z to each side) \ \

\

\"\"         (Commutative property of addition: \"\")   

\

\"\"                              (Additive inverse property: \"\")

\

\"\"                                       (Add: \"\")\"\" 

\

\"\"                                  (Divide each side by 8)

\

\"\"                                       (Cancel common terms) \ \

\

\"\"                                       (Divide: \"\")\"\"

\
\

Check:-

\

To check the solution substitute \"\" in equation \"\".

\

\"\"      (Substitute \"\" ) \ \

\

\"\"                         (Multiply: \"\") \ \

\

\"\"                                   (Subtract: \"\")

\

Hence the solution is true. \ \ \"\"

\
\

The solution is \"\". \ \
