Homework Statement
I've attached the problem.
Homework Equations
L(1) = 1 /s
L(t^n) = n!/s^(n+1)
The Attempt at a Solution
because the question only asks for X(s) I only considered the x' + x + 4y=3 equation.
I applied laplace tranforms and got:
s X(s) - x(0) + 1/s^2 + 4/s^2 = 3/s. since x(0) = 0 it gets canceled out so..
s X(s) + 5/s^2 = 3/s
s X(s) = 3/s - 5/s^2
therfore
X(s) = (3/s - 5/s^2) / s
only problem is, i didn't use the other equation which makes me feel I've done it wrong.
