83x + P = 83x + Q <em>subtract 83x from both sides</em>
P = Q
The equation has no solution for P different Q (P ≠ Q).
Use the desmos calculator it will really help for graphing things
The area of the surface given by is 1. In terms of a surface integral, we have
By multiplying each component in by 5, we have
and the same goes for the derivative with respect to . Then the area of the surface given by is
