Solve the differential equation.<br><br> dx/dt = 1 - t + x - tx
dem82 [27]
\displaystyle\frac{dx}{dt} = 1 - t + x - tx\ \Rightarrow\ \frac{dx}{dt} = 1(1- t) + x(1 - t) \ \Rightarrow \\ \\ &#10;\frac{dx}{dt} = (1+x)(1 - t) \ \Rightarrow\ \int \frac{dx}{1+x} = \int (1 - t)\ dt\ \Rightarrow \\ \\ \textstyle&#10;\ln|1 + x| = t - \frac{1}{2}t^2 + C\ \Rightarrow\ |1 + x| = e^{t - t^2/2 + C }\ \Rightarrow \\ \\&#10;1 + x = \pm e^{t - t^2/2} \cdot e^C\Rightarrow \\ \\ x = -1 + Ke^{t - t^2/2},\ \text{where $K$ is any nonzero constant.}
