Determine whether the equation is exact. If it is, then solve it. e'(5y - 71)dt + (6 + 5 e ') dy 0 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The equation is exact and an implicit solution in the form F(t.y) = C is= C, where C is an arbitrary constant. (Type an expression using t and y as the variables.) B. The equation is not exact.
