Explanation Given Information: The provided linear differential equation is y ′ − 3 y = − 2 . Formula used: The standard form of a first-order linear differential equation is, y ′ + P ( x ) y = Q ( x ) Where, P and Q are the continuous function of x . Method 1: Steps to solve a first-order linear differential equation: Step 1: Write the equation in standard form, y ′ + P ( x ) y = Q ( x ) Step 2: Now compare the provided equation with standard equation and write the values of the function P and Q . Step 3: Then find the integrating factor, u ( x ) = e ∫ P ( x ) d x Step 4: Now, solve the integral below in order to get the general solution y = 1 u ( x ) ∫ Q ( x ) u ( x ) d x And y ′ = d y d x Method 2: Steps to solve a first-order linear differential equation by separation of variables: Step 1: Write the equation in standard form, d y d x = f ( x ) g ( y ) Step 2: Now separate the variables in such a way that the variable x on one side and variable y on another side as, d y g ( y ) = f ( x ) d x . Step 3: Integrate each side as ∫ d y g ( y ) = ∫ f ( x ) d x . Step 4: Now, solve the integral below in order to get the general solution ∫ d y g ( y ) = ∫ f ( x ) d x + C Calculation: Method 1: Consider the provided linear differential equation, y ′ − 3 y = − 2 Now compare the provided equation y ′ − 3 y = − 2 with standard equation y ′ + P ( x ) y = Q ( x ) . Here, P ( x ) = − 3 and Q ( x ) = − 2 Therefore, the integrating factor is, u ( x ) = e ∫ P ( x ) d x Now, substitute the value of the function P ( x ) = − 3 in the equation u ( x ) = e ∫ P ( x ) d x . Therefore, u ( x ) = e ∫ − 3 d x = e − 3 ∫ d x = e − 3 x Thus, u ( x ) = e − 3 x Now apply the formula of the general equation, y = 1 u ( x ) ∫ Q ( x ) u ( x ) d x Substitute the values of integrating factor u ( x ) , continuous function P ( x ) and Q ( x ) in the formula of the general equation y = 1 u ( x ) ∫ Q ( x ) u ( x ) d x
