Some say that to brew an excellent cup of coffee, you must have a brewing temperature off 200 degrees, plus or minus five degrees. write and solve an equation describing the maximum and minimum brewing temperatures for an excellent cup of coffee

Your equation for the maximum brewing temperature should be x = 200 + 5 because according to your word problem, the temp. can be five degrees above 200 degrees. 

x = 200 + 5 
x = 205

Your equation for the minimum brewing temperature should be x = 200 - 5 because according to your word problem, the temp. can be five degrees below 200 degrees.

x = 200 - 5
x = 195
