Homework Statement
I keep getting the wrong answer, and wolphram seems to back me up.
Here's the system of equations
##(-10+s)X(s)-7Y(s)=\frac{10}{s}##
##X(s)+(-2+s)Y(s)=0##
Homework Equations
The Attempt at a Solution
Using Cramer's rule I've got
##X(s)=\frac{10}{(s-9)(s-3)}-\frac{20}{s(s-9)(s-3)}##
Using partial fraction decomposition I've got
##x(t)=e^{9t}(10/6-20/54)+e^{3t}(-10/6+20/18)-20/27##
Evaluating ##x(1)## I get ##10492.1##
