  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 🙂
