soal
3c,3d,4a dab 4c
tolong bantu jawab ka
Jawaban:
3c. ordo 4×3 (transpos tulis ulang baris sebagai kolom)
3d. ordo 3×2 (transpos tulis ulang baris sebagai kolom)
4a.
[tex]2a - 1 = 7 - 2a \\ 2a + 2a = 7 + 1 \\ 4a = 8 \\ a = \frac{8}{4} \\ a = 2[/tex]
[tex]4b + 2 = - 10 \\ 4b = - 10 - 2 \\ 4b = - 12 \\ b = - 3[/tex]
4c.
[tex]a - 1 = 2 \\ a = 2 + 1 \\ a = 3[/tex]
jelas
[tex]2b = a + 3 \\ 2b = 3 + 3 \\ b = \frac{6}{2} \\ b = 3[/tex]
jelas
[tex]6c + b = 5 \\ 6c + 3 = 5 \\ 6c = 5 - 3 \\ c = \frac{2}{6} = \frac{1}{3} [/tex]
