Ответ:
А) x1=-7, x2=8;
Б) х1=-5/3, х2=3.
Пошаговое объяснение:
А)
[tex] |1 - 2x| - 7 = 8 \\ |1 - 2x| = 8 + 7 \\ | 1 - 2x| = 15 \\ 1 - 2x = 15 \\ 1 - 2x = - 15 \\ x1 = - 7 \\x2 = 8[/tex]
Б)
[tex]12 - |2 - 3x| = 5 \\ - |2 - 3x| = 5 - 12 \\ - |2 - 3x| = - 7 \\ |2 - 3x| = 7 \\ 2 - 3x = 7 \\ 2 - 3x = - 7 \\ x1 = - \frac{5}{3} \\ x2 = 3[/tex]
