Final answer:
To solve the given differential equation and express it in the form y + P(t)y = Q(t)y, we first divide both sides of the equation by y. Next, we multiply both sides of the equation by y to eliminate the fraction.
Step-by-step explanation:
The first step to solve the given differential equation and express it in the form y + P(t)y = Q(t)y is to divide both sides of the equation by y. This gives us:
(1/y) * dy/dt + P(t) = Q(t)
Next, we can multiply both sides of the equation by y to eliminate the fraction:
dy/dt + P(t)y = Q(t)y
