Nilai x Yg memenuhi |2X- 6| - | 3x + 8 | = 0 adalah

Nilai x Yg memenuhi |2X- 6| – | 3x + 8 | = 0 adalah

Jawaban:

x= -14 atau x= -2/5

Penjelasan dengan langkah-langkah:

|2x-6| – |3x+8| = 0

|2x-6| = |3x+8|

$sqrt{2x - 6} {}^{2} = sqrt{3x + 8} {}^{2} \ (2x - 6) {}^{2} = (3x + 8) {}^{2} \ 4 {x}^{2} - 24x + 36 = 9 {x}^{2} + 48x + 64 \ - 5 {x}^{2} - 72x - 28 = 0 \ 5 {x}^{2} + 72x + 28 = 0 \ frac{1}{5} (5x + 70)(5x + 2) = 0\ (x + 14)(5x + 2) = 0 \ x = - 14 : atau : x = - frac{2}{5}$

Jawab:

|2x- 6| – | 3x + 8 | = 0

2x-6-3x+8 =0

2x-3x=6-8

-x=-2

x=2
