\"\"\"\"

\

The equation is, \"\"

\

Using distributive property multiply the factors: \"\"

\

\"\"

\

\"\"        (Multiply the factors)

\

\"\"        (Apply Commutative property: \"\")

\

\"\"               (Subtract: \"\")

\

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

\

\"\"

\

\"\"        (Add 61 to both sides)

\

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

\

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

\

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

\

\"\"                             (Divide each side by 4)

\

\"\"                                      (Cancel cammon terms)

\

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

\

\"\"                          (Multiply each side by negative one)

\

\"\"                                   (Product of two same signs is positive)

\

\"\"

\

Check:

\

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

\

 \"\"              (Substutite \"\")

\

 First evaluate inside the brackets

\

 \"\"   

\

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

\

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

\

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

\

\"\"

\

The solution is \"\".
