QUIZ (1413)
Materi: Nilai Mutlak

Tentukan penyelesaian dari [tex] \displaystyle |14y-13|=1 [/tex] !​

Answer 1

Penjelasan dengan langkah-langkah:

[tex] |14 y - 13| = 1 \\ \\ 14y - 13 = 1 \\ 14y= 1 + 13 \\ 14y = 14 \\ y = \frac{14}{14} \\ y = 1 \\ \\ 14y - 13 = - 1 \\ 14y = - 1 + 13 \\ 14y = 12 \\ y = \frac{12}{14} \\ y = \frac{6}{7} [/tex]

Answer 2

Verified answer

Jawaban:

y = {6/7, 1}

Penjelasan dengan langkah-langkah:

|14y - 13| = 1

-14y + 13 = 1

[tex] - 14y + 13 - 1 = 0[/tex]

[tex] - 14y + 12 = 0[/tex]

[tex]y - \frac{12}{14} = 0[/tex]

[tex]y - \frac{6}{7} = 0[/tex]

[tex]y = \frac{6}{7} [/tex]

14y - 13 = 1

14y - 13 - 1 = 0

14y - 14 = 0

y - (14 ÷ 14) = 0

y - 1 = 0

y = 1

Penyelesaian: y = {6/7, 1}
