Hi everyone. I got a problem with the problem 786, I need your help.
\(\displaystyle \mbox{786. }\, \dfrac{dx}{dt}\, +\, \dfrac{2x}{t}\, =\, 1\)
. . . .\(\displaystyle \dfrac{dy}{dt}\, =\, x\, +\, y\, +\, \dfrac{2x}{t}\, -\, 1\)
I have addded up the equations and got x+y=e^t. What should I do then?
