Question

bantuin donggg pakai cara kerja nya dan jangan ngasal ​

Answer 1

Jawab:

   [tex]\vec{c}=\left(\begin{array}{c}-1\\-3\\-2\end{array}\right)[/tex]

[tex]x+y+z= -4[/tex]

Penjelasan dengan langkah-langkah:

[tex]\vec{c}+\vec{b}=\vec{b}-\vec{a}[/tex]

[tex]\vec{c}=\vec{b} - \vec{b}-\vec{a}[/tex]

[tex]\vec{c}=-\vec{a}[/tex]

[tex]\vec{c}=-\left(\begin{array}{c}1\\3\\2\end{array}\right)[/tex]

[tex]\vec{c}=\left(\begin{array}{c}-1\\-3\\-2\end{array}\right)[/tex]

[tex]\left(\begin{array}{c}x-2\\y+1\\z-1\end{array}\right)=\left(\begin{array}{c}-1\\-3\\-2\end{array}\right)[/tex]

[tex]x-2=-1[/tex]

[tex]x=-1+2=1[/tex]

[tex]y+1 = -3[/tex]

[tex]y=-3-1=-4[/tex]

[tex]z-1=-2[/tex]

[tex]z=-2+1=-1[/tex]

[tex]x+y+z=1 -4 -1 = -4[/tex]
