Help ! Have 2 problems on tomorrow's exam similar to these 2 and I haven't been able to get anywhere with them in 2 days ! Please show me the steps so I don't bomb ! Thanks !

1)

Find the solution to the system:

x'-2x-y'-y=6*exp^(3t)

2x'-3x+y'-3y=6*exp^(3t)

satisfying the condition x(0)=3 and y(0)=0

2)

solve

y'+4y=4t^2-4t+10
