\"\"

\

The equation is,\"\"

\

Using distributive property : \"\".

\

\"\"                  

\

\"\"         (Multiply the factors)

\

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

\

Subtraction property of equality: If a = b then a - c = b - c

\

\"\"               (Subtract 3 from both sides)

\

\"\"                         (Apply Additive inverse property: a + (-a) = -a + a = 0 )

\

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

\

\"\"                          (Divide both sides by \"\")

\

\"\"                                  (Cancel common terms)

\

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

\

\"\"
