• Division always comes before addition unless there are brackets. Integration by substitution is not required for this integral. ∫ (e˟ / 1 + e˟) dx ∫ (e˟ + e˟) dx ∫ 2e˟ dx 2 ∫ e˟ dx 2e˟ + C

• Well done, you have simplified the expression as far as possible.

• Integration by substitution is not required because it is only a linear function within the beacket. Simply integrate as normal then divide by the derivative of the bracket. ∫ e ^ (2 - x) dx e ^ (2 - x) / -1 + C -e ^ (2 - x) + C

• There is no need for brackets around single terms as you have here. Find the general solution by separating the variables then integrating: 6y(dy / dx) = 7x² - 3x + 9 y dy = (7x² / 6 - x / 2 + 3 / 2) dx ∫ y dy = ∫ (7x² / 6 - x / 2 + 3 / 2) dx …
