Розв'яжіть рівняння: 1) (2х — 1) (15 + 9x) - 6x (3х - 5) = 87;
2) (14х — 1) (2 + х) = (2x – 8) (7х + 1);
3) (х + 10) (х – 5) - (х – 6) (х + 3) = 16;
4) (3х + 7) (8х + 1) = (6x - 7) (4x - 1) + 93x
2) (14х — 1) (2 + х) = (2x – 8) (7х + 1);
3) (х + 10) (х – 5) - (х – 6) (х + 3) = 16;
4) (3х + 7) (8х + 1) = (6x - 7) (4x - 1) + 93x
