Pregunta: 7. Solve the D.E. dxdy−y=811e−3x;y(0)=−1

Given D.E is $\frac{\mathrm{d}\mathrm{y}}{\mathrm{d}\mathrm{x}}-\mathrm{y}=\frac{11}{8}{\mathrm{e}}^{-\frac{\mathrm{x}}{3}}\text{and}\mathrm{y}\left(0\right)=-1$

This is a linear differential equation of the first order of the form $\frac{\mathrm{d}\mathrm{y}}{\mathrm{d}\mathrm{x}}+\mathrm{P}\mathrm{y}=\mathrm{Q},$ where P and Q ar...
