Дифференциалдық теңдеудін жалпы шешімін табыңыз:
(x+7)y′=y+9(x + 7)y' = y + 9(x+7)y′=y+9
y=C(x+7)+9y = C(x + 7) + 9y=C(x+7)+9
y=C(x+7)−9
y=C(x+7)−63
y=C(x+7)2−9

Жалпы шешімін табыңыз: eyy′=5exe^y y' = 5e^xeyy′=5ex
ey=5ex+C
ey=e5x+Ce^y = e^{5x} + Cey=e5x+C
y=5x+C
y=ln(5ex+C)y = \ln(5e^x + C)y=ln(5ex+C)
