The ideal temperature for roasting cocoa beans is \"\" plus or minus \"\".

\

Describing the maximum and minimum roasting temperatures for cocoa beans.

\

Write an equation.

\

The equation is \"\".

\

Solve the equation.

\

\"\"                           (Original equation)

\

Case(i):

\

\"\"                            (First equation) 

\

\"\"       (Add \"\" to each side)

\

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

\

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

\

Case(ii):

\

\"\"                        (Second equation)

\

\"\"   (Add \"\" to each side)

\

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

\

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

\

So, the maximum temperature is \"\" and the minimum temperature is \"\".

\

\"\"

\

The maximum temperature is \"\" and the minimum temperature is \"\".
