Hi there,

Id really appreciate help with these two particular questions.. ive been trying to figure them out for two days! Please help! :(

{5 -1 -1 -8 : 5 }
{10 -2 4 2 : 8}


And the second one is :

{ 1 -2 1 -4 : -3}
{ 1 3 7 2 : 18}
{ 1 -12 -11 -16 : -37}

{1 -1/5 -1/5 -8/5 :1}
{-5 1 -2 -1 :-4}

{1 -1/5 -1/5 -8/5 :1}
{0 0 -3 -9 : 1}

{1 1 1 8 :-5}

The second one..

{1 -2 1 -4 :-3}
{0 5 6 6 :21}
{0 -10 -12 -12 : -34}


{1 -2 1 -4 : -3}
{0 1 6/5 6/5 :21/5}
{0 5 6 6 : 17}


{1 -2 1 -4 :-3}
{0 1 6/5 6/5 :21/5}
{0 0 0 0 : -4)
