Multiple Choice

The solution of the system dxdt=5x+y,dydt=3x+3y\frac { d x } { d t } = 5 x + y , \frac { d y } { d t } = 3 x + 3 y is


A) x=c1e6t+c2e2t,y=c1e6t3c2e2tx = c _ { 1 } e ^ { - 6 t } + c _ { 2 } e ^ { - 2 t } , y = c _ { 1 } e ^ { - 6 t } - 3 c _ { 2 } e ^ { - 2 t }
B) x=c1e6t+c2e2t,y=c1e6t3c2e2tx = c _ { 1 } e ^ { 6 t } + c _ { 2 } e ^ { 2 t } , y = c _ { 1 } e ^ { 6 t } - 3 c _ { 2 } e ^ { 2 t }
C) x=c1e6t3c2e2t,y=c1e6t+c2e2tx = c _ { 1 } e ^ { - 6 t } - 3 c _ { 2 } e ^ { - 2 t } , y = c _ { 1 } e ^ { - 6 t } + c _ { 2 } e ^ { - 2 t }
D) x=c1e6t3c2e2t,y=c1e6t+c2e2tx = c _ { 1 } e ^ { 6 t } - 3 c _ { 2 } e ^ { - 2 t } , y = c _ { 1 } e ^ { 6 t } + c _ { 2 } e ^ { - 2 t }
E) x=c1e6t+c2e2t,y=c1e6t3c2e2tx = c _ { 1 } e ^ { 6 t } + c _ { 2 } e ^ { - 2 t } , y = c _ { 1 } e ^ { 6 t } - 3 c _ { 2 } e ^ { - 2 t }
