Answer 1

Respuesta:

Explicación paso a paso:

A) 2k + 7 = 12 -73

2k +7 = 61

2k = 56

k = 28

B) 10 - 4x = 7 - 6x

10 - 4x - 7 = - 6x

3 - 4x = -6x

3 = -2x

- 3/2 = x

x = -3/2

C) 5m-3,2 = 2m + 2,8

5m - 2m = 2,8 + 3,2

3m = 6

m = 6/3

m = 2

D) 5n - 2n + 12 = 35 - 4n - 9

3n + 12 = 26 - 4n

3n + 4n = 26 - 12

7n = 14

n = 2

E) 3ñ - 152ñ - 14ñ = -11

3ñ -166ñ = -11

- 163ñ = -11

ñ = -11/-163

ñ = 11/ 163

F) 48p -13 +12p = 72p -3 -24p

60p - 13 = 96p - 3

60p - 96p = -3 + 13

36p = 10

p = 10/36

p = 5/18

G) q -3 + 6q -9 +12q -15 = 9

19q -27= 9

16q = 9 + 27

16q = 36

q = 36/16

q = 9/4

H) 6r +12r -9 -8r +10 +r = 0

19r - 8r -9 + 10 = 0

11r + 1 = 0

11r = -1

r = - 1/11
