Найдите корни уравнения 2 - 3(2x + 2) = 5 - 4x.

1. $2 - 3(2x + 2) = 5 - 4x$ $2 - 6x - 6 = 5 - 4x$ $-4 - 6x = 5 - 4x$ $-2x = 9$ $x = -4,5$ **Ответ: -4,5** 2. $5 - 2x = 11 - 7(x + 2)$ $5 - 2x = 11 - 7x - 14$ $5 - 2x = -7x - 3$ $5x = -8$ $x = -1,6$ **Ответ: -1,6** 3. $3x + 5 + (x + 5) = (1 - x) + 4$ $4x + 10 = 5 - x$ $5x = -5$ $x = -1$ **Ответ: -1** 4. $10x + 9 = 7x$ $3x = -9$ $x = -3$ **Ответ: -3** 5. $-x - 2 + 3(x - 3) = 3(4 - x) - 3$ $-x - 2 + 3x - 9 = 12 - 3x - 3$ $2x - 11 = 9 - 3x$ $5x = 20$ $x = 4$ **Ответ: 4** 6. $7x - 2 = 3x + 6$ $4x = 8$ $x = 2$ **Ответ: 2** 7. $10(x - 9) = 7$ $10x - 90 = 7$ $10x = 97$ $x = 9,7$ **Ответ: 9,7** 8. $-9(8 - 9x) = 4x + 5$ $-72 + 81x = 4x + 5$ $77x = 77$ $x = 1$ **Ответ: 1** 9. $1 - 5x = -6x + 8$ $x = 7$ **Ответ: 7** 10. $9 - 2(-4x + 7) = 7$ $9 + 8x - 14 = 7$ $8x - 5 = 7$ $8x = 12$ $x = 1,5$ **Ответ: 1,5**
