himpunan penyelesaian 3 variabel menggunakan cara eliminasi 3y-2z=-4 dan 12y -6z=-18

[tex]3y - 2z = - 4 \: \: \: \: \: \: \: | \times 4| \\ \frac{12y - 6z = - 18}{} - \\ 12y - 8z = - 16 \\ \frac{12y - 6z = - 18}{ - 2z = 2} - \\ \frac{ - 2z}{ - 2 } = \frac{2}{ - 2} \\ z = - 1 \\ \\ 3y - 2z = - 4 \: \: \: \: \: | \times 3| \\ \frac{12y - 6z = - 18}{} - \\ 9y - 6z = - 12 \\ \frac{12y - 6z = - 18}{ - 3y = 6} - \\ \frac{ - 3y}{ - 3} = \frac{6}{ - 3} \\ y = - 2[/tex]

smogaa membantuu:D
maaf kaloo salahh:v
