Question

ME AJUDEM PFVR!!!!!!!!!!!! S2

Answer 1

{X+2y-3z=10

{-3y+7z=-17

{4z=-8---->z=-2

-3y+7(-2)=-17

-3y-14=-17

-3y=--3

-3y=3

y=1

X+2×1-3×(-2)=10

X+2+6=10

X+8=10

X=2

V={2,1,-2}

Answer 2

Resposta:

x+2y-3z=10

-3y+7z=-17

4z=-8

então:

4z=-8

z=-8/4

z=-2

-3y+7z=-17

-3y+7.-2=-17

-3y-14=-17

-3y=-17+14

(-3y=-3).-1

3y=3

y=3/3

y=1

x+2y-3z=10

x+2.1-3.-2=10

x+2+6=10

x+8=10

x=10-8

x=2
