The given equation is \"\"

\

\"\"                             (Distributive property: \"\")

\

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

\

\"\"                   (Subtract 4b from each side)

\

\"\"                   (Commutative property: a + b = b + a) \ \

\

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

\

\"\"                               (Additive identity property: \"\")

\

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

\

\"\"                         (Subtract 6 from each side)

\

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

\

\"\"                                    (Additive identity property: \"\")

\

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

\

\"\"                                      (Divide each side by nagative 2)

\

\"\"                                                (Cancel common terms and flip the symbol)

\

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

\

Verify:-

\

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

\

  \"\"                           (Substitute  b=4)

\

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

\

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

\

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

\

  Compare the values, the equation is true. The solution is\"\"

\

  \"\"

\

  The value of b is \"\".
