Isi titik-titik di bawah!

a = ...
b = ...
c = ...​

Jawaban:

a = 4

b = 6

c = 12

Penjelasan dengan langkah-langkah:

a + b + c = 22

3a = c

a + b = 10

[tex]________________[/tex]

nilai c

[tex] \sf a + b + c = 22 \\ \sf \frac{a + b = 10}{c = 12} - [/tex]

[tex]________________[/tex]

nilai a

3a = c

a = c/3

a = 12/3 = 4

[tex]________________[/tex]

nilai b

a + b = 10

4 + b = 10

b = 10 - 4

b = 6

Jawaban:

a = 4

b = 6

c = 12

Penjelasan dengan langkah-langkah:

metode Determinan matriks ordo 3×3

semoga benar ^^
