The temperature at which porcelain pot is fired is 2552° F.
Firstly forming the equation to find the temperature at which the porcelain pot is fired. Secondly we will solve the equation based on operators. Let us represent the required temperature by t.
t = 2×1409 - 266
Performing multiplication on Right Hand Side of the equation to find the value of t
t = 2818 - 266
Performing subtraction on Right Hand Side of the equation to find the value of t
t = 2552
Based on the temperature, the porcelain pot is fired at 2552° F.
