Explanation Definition used: For first order linear differential equation of the form y ' ( x ) + P ( x ) y = Q ( x ) . And the solution will be of the form y ( x ) = ∫ e ∫ P ( x ) d x Q ( x ) d x + C e ∫ P ( x ) d x . Calculation: Consider the given differential equation is y ′ ( t ) = y − t . To solve first order linear differential equation P ( t ) = − 1 , Q ( t ) = − t , y ( t ) = ∫ e − ∫ d t ( − t ) d t + C e − ∫ d t y ( t ) = ∫ e − t ( − t ) d t + C e − t
