Question

25PUNTOS AYUDENMEEEE!
a) 7x + 12 = 2x + 27

b) 4x + 8 = 8x + 2

c) 3x + 40 = 12x – 14

d) - 2(z – 6) = - 36

e) 2(6m + 4) + 6 = 4(2m – 4) - 14​

Answer 1

Explicación paso a paso:

a) 7x + 12 = 2x + 27

7x - 2x = 27 - 12

5x = 15

x = 15/5

x = 3

b) 4x+8 = 8x + 2

8 - 2 = 8x - 4x

6 = 4x

6/4 = x (simplificando)

3/2 = x

c) 3x + 40 = 12x - 14

40 + 14 = 12x - 3x

54 = 9x

54/9 = x

6 = x

D) -2( z - 6 ) = -36

-2z + 12 = -36

12 + 36 = 2z

48 = 2z

48/2 = z

24 = z

E) 2 ( 6m + 4 ) + 6 = 4 (2m - 4) - 14

12m + 8 + 6 = 8m - 16 - 14

12m + 14 = 8m - 30

12m - 8m = -30 -12

4m = - 44

m = 11

MEDIA HORA ESCRIBIENDO XDXD......PERO ESPERO HABERTE AYUDADO :)
