| A. | ( frac{dy(t)}{dt} + y(t) = frac{dx(t)}{dt} + 3x(t) ) |
| B. | ( frac{dy(t)}{dt} + 2y(t) = frac{dx(t)}{dt} + 3x(t) ) |
| C. | ( frac{dy(t)}{dt} y(t) = frac{dx(t)}{dt} + 3x(t) ) |
| D. | ( frac{dy(t)}{dt} 2y(t) = frac{dx(t)}{dt} + 3x(t) ) |
| Answer» B. ( frac{dy(t)}{dt} + 2y(t) = frac{dx(t)}{dt} + 3x(t) ) | |
