2.-3x-4=-0,5
3.-(x-1)-(2x+3)=x
4.-(3x+3)-(-4x+4)=-(6x+6)
С ПРОВЕРКОЙ

Answer 1

1)

$- 6x - 5x = - 6 - 12$

$- 11x = - 18$

$x = \frac{18}{11} = 1 \frac{7}{11}$

2)

$- 3x = - 0.5 + 4$

$- 3x = 3.5$

$x = - \frac{35}{30} = - 1 \frac{1}{6}$

3)

$- x + 1 - 2x - 3 = x$

$- x - x - 2x = 3 - 1$

$- 4x = 2$

$x = - 0.5$

4)

$- 3x - 3 + 4x - 4 = - 6x - 6$

$- 3x + 4x + 6x = 3 + 4 - 6$

$7x = 1$

$x = \frac{1}{7}$
