Question

helpppp esto es muy urgente

Answer 1

Espero te ayude

Explicación paso a paso:

1. -7x - 42 - 5 = - 19

-7x -47 = -19

-7x = 28

x = -4

2. 8k - 24 + 12 = - 28

8k -12 = -28

8k = -16

k = -2

3. -45 + 9x + 3 = 3x - 6

-42 + 9x = 3x - 6

6x = 36

x = 6

4. 2m - 6 - 3m = 5

-m = 11

m = -11

5. 8x - 30 = 2x - 6

6x = 24

x = 4

Answer 2

Respuesta:

1) - 7(x +6) - 5 =-19

- 7x + - 42 - 5 =-19

-7x + - 47 = - 19

-7x = - 19 - (-47)

-7x = 28

X = 28/ - 7

X = - 4

2) 8 (k-3)+12=-28

8k - 24 +12 =-28

8k - 12 = - 28

8k = - 28 +12

8k = - 16

K= - 16/8

K= - 2

3) - 9(5-x) +3 = 3x - 6

-45 + 9x +3 =3x - 6

-45+3 +6 = 3x - 9x

-36= - 6 x

X = - 36 /6

X = - 6

4) 2(m-3)- 3m =5

2m - 6 - 3m =5

2m - 3m =5+6

-1m = 11

M= 11/-1

M= - 1

5) 8x - 30=2 (x-3)

8x - 30= 2x - 6

8x + 2x = - 6 +30

10x = 24

X = 24 / 10

X = 2,4
