Q12. Solve the differential equation .
Given, [e−2xx−yx]dxdy=1 ⇒dydx=e−2xx−yx ⟹dydx+yx=e−2xx This is equation is in the form of dydx+py=Q p=1x and Q=e−2xx Now, I.F. =e∫pdx=e∫1xdx=e2x We know that the solution of the given differential equation is: y(I⋅F.)=∫(Q⋅F⋅)dx+C ⇒ye2x=∫(e−2xx×e2x)dx+C ⇒ye2x=∫1xdx+C ⇒ye2x=2x+C
