Matematika persamaan nilai mutlak

Jawab:

1. HP x = {-8/3, -2}

2. HP x = {-7/2, -3/2}

3. HP x = {-5, 10}

Penjelasan dengan langkah-langkah:

1. | 3x + 7 | = 1

[tex]3x + 7 = 1 \\3x = -6 \\x = -2 \\atau \\3x + 7 = -1 \\3x = -8 \\x = -\frac{8}{3}[/tex]

2. | 2x + 5 | = 2

[tex]2x + 5 = 2 \\2x = -3 \\x = -\frac{3}{2} \\atau \\2x + 5 = -2 \\2x = -7 \\x = -\frac{7}{2}[/tex]

3. | 5 - 2x | = 15

[tex]5 - 2x = 15 \\-2x = 10 \\x = -5 \\atau \\5 - 2x = -15 \\-2x = -20 \\x = 10[/tex]
