Jawaban = C
x + y = 4 + 2 = 6
Penjelasan dengan langkah-langkah:
[tex] \frac{x - 2}{2} + \frac{y + 4}{3} = 3 \\ \frac{3x - 6 + 2y + 8}{6} = 3 \\ 3x + 2y + 2= 18 \\3x + 2y = 16 \: \: \: \: \: \: (i) \\ \frac{x + 4}{4} = y \\ x + 4 = 4y \\ x - 4y = - 4 \: \: \: \: \: \: \: \: (ii)[/tex]
eliminasi x dari pers (i) dan (ii) [×3]
[tex]3x + 2y = 16 \\ 3x - 12y = - 12[/tex]
[tex]14y = 28 \\ y = 2[/tex]
Subtitusi nilai y = 2
[tex]3x + 2y = 16 \\ 3x + 2(2) = 16 \\ 3x = 12 \\ x = 4[/tex]
