\

The equation is, \"\"

\

Using distributive property multiply the factors: \"\".

\

\"\"                     

\

\"\"                        (Multiply the factors)

\

\"\"                                      (Subtract: \"\". Add:\"\")

\

\

Addition property of equality: If a = b then a + c = b + c

\

\"\"                      (Add 10 to each sides)

\

\"\"                                              (Subtract: \"\". Add:\"\")

\
