Answer 1

Ответ:

1) -3х=9

х=9:-3

х=-3

2)6х=-3

х=-2

3)-3х=-3

х=1

4)2х+2=3

2х=1

х=1/2

5)9-6+8х=-2х+1

10х=-2

х=-5

Answer 2

$- 3x - 2 = 7$

$- 3x = 9$

$x = - 3$

2)

$4x + 3 = 2x$

$2x = - 3$

$x = - 1.5$

3)

$6 - 5x = - 2x + 9$

$3x = - 3$

$x = - 1$

4)

$2(x + 1) = 3$

$2x + 2 = 3$

$2x = 1$

$x = \frac{1}{2}$

5)

$9 - 2(3 - 4x) = - 2x + 1$

$9 - 6 + 8x = - 2x + 1$

$10x = - 2$

$x = - 0.2$
