some say that to brew an excellent cup of coffee, you must have a brewing temperature off 200 degrees, plus or minus five degree
ASHA 777 [7]
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

Solve each equation, sho<br> 5) 2x – 0,5 = 3.7
soldier1979 [14.2K]
Add 0.5 to 0.5 and 3.7 to make X by itself

3.7 + 0.5 is 4.2

4.2 / 2 (because you get X by itself

X = 2.1
