Решите уравнения: 1) x + 3 = −9x; 2) −3x − 9 = 2x; 3) 6x + 1 = −4x; 4) −2x − 4 = 3x; 5) 3x + 3 = 5x; 6) −8x − 3 = −6x; 7) 7 + 8x = −2x − 5; 8) −5 + 9x = 10x + 4; 9) 1 − 10x = −5x + 10; 10) −4 − 6x = 4x − 3; 11) 2 + 3x = −7x − 5; 12) −1 − 3x = 2x + 1.
- \(x+3=-9x\); \(10x=-3\); \(x=-\frac{3}{10}\).
- \(-3x-9=2x\); \(-5x=9\); \(x=-\frac{9}{5}\).
- \(6x+1=-4x\); \(10x=-1\); \(x=-\frac{1}{10}\).
- \(-2x-4=3x\); \(-5x=4\); \(x=-\frac{4}{5}\).
- \(3x+3=5x\); \(3=2x\); \(x=\frac{3}{2}\).
- \(-8x-3=-6x\); \(-3=2x\); \(x=-\frac{3}{2}\).
- \(7+8x=-2x-5\); \(10x=-12\); \(x=-\frac{6}{5}\).
- \(-5+9x=10x+4\); \(-9=x\); \(x=-9\).
- \(1-10x=-5x+10\); \(-5x=9\); \(x=-\frac{9}{5}\).
- \(-4-6x=4x-3\); \(-10x=1\); \(x=-\frac{1}{10}\).
- \(2+3x=-7x-5\); \(10x=-7\); \(x=-\frac{7}{10}\).
- \(-1-3x=2x+1\); \(-5x=2\); \(x=-\frac{2}{5}\).
