Answer 1

-X = -2

x=2

~°~

-3x = 10

3x= -10

x=-10/3

~°~

-7 x = -14

7x =14

x = 14/7

x = 2

~°~

-5 x = -12

5x = 12

x = 12/5

~°~

-4 x= 8

4x = -8

x= -8/4

x = -2

~°~

-3 x = -9

3x = 9

x=9/3

x=3

~°~

-5 x = 15

5x= -15

x=-15/5

x= 3

~°~

-2 x = -10

2x = 10

x = 10/2

× = 5

~°~

15 = -3 x

3x= -15

x=-15/3

x=-5

~°~

-40 = -5 x

5x = 40

x= 40/5

x=8

Answer 2

Resposta:

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

$- 3x = 10 \\ x = - \frac {10}{ 3}$

$- 7x = - 14 \\ x = \frac{ - 14}{ - 7} \\ x = 2$

$- 5x = - 12 \\ x = \frac{ - 12}{ - 5} \\ x = \frac{12}{5}$

$- 4x = 8 \\ x = \frac{8}{ - 4} \\ x = - 2$

$- 3x = - 9 \\ x = \frac{ - 9}{ - 3} \\ x = 3$

$- 5x = 15 \\ x = \frac{15}{ - 5} \\ x = - 3$

$- 2x = - 10 \\ x = \frac{ - 10 }{ - 5} \\ x = 2$

$15 = - 3x \\ \frac{15}{ - 3} = x \\ \\ - 5 = x$

$- 40 = - 5x \\ \frac{ - 40}{ - 5} = x \\ \\ 8 = x$
