Решите уравнения: 3x+3=5x; 2+3x=-7x-5; 10(x+2)=-7; -8x-3=-6x; -1-3x=2x+1; 5(x-6)=2; x-x/7=6; x-x/12=11/3; x-x/11=50/11

1. **Ответ: $x = 1,5$** $3x + 3 = 5x$ $3x - 5x = -3$ $-2x = -3$ $x = 1,5$ 2. **Ответ: $x = -0,7$** $2 + 3x = -7x - 5$ $3x + 7x = -5 - 2$ $10x = -7$ $x = -0,7$ 3. **Ответ: $x = -2,7$** $10(x + 2) = -7$ $10x + 20 = -7$ $10x = -7 - 20$ $10x = -27$ $x = -2,7$ 4. **Ответ: $x = -1,5$** $-8x - 3 = -6x$ $-8x + 6x = 3$ $-2x = 3$ $x = -1,5$ 5. **Ответ: $x = -0,4$** $-1 - 3x = 2x + 1$ $-3x - 2x = 1 + 1$ $-5x = 2$ $x = -0,4$ 6. **Ответ: $x = 6,4$** $5(x - 6) = 2$ $5x - 30 = 2$ $5x = 32$ $x = 6,4$ 7. **Ответ: $x = 7$** $x - \frac{x}{7} = 6$ $\frac{6x}{7} = 6$ $6x = 42$ $x = 7$ 8. **Ответ: $x = 4$** $x - \frac{x}{12} = \frac{11}{3}$ $\frac{11x}{12} = \frac{11}{3}$ (умножим обе части на 12) $11x = 44$ $x = 4$ 9. **Ответ: $x = 5$** $x - \frac{x}{11} = \frac{50}{11}$ $\frac{10x}{11} = \frac{50}{11}$ (умножим обе части на 11) $10x = 50$ $x = 5$
