Answer 1

Respuesta:

A) x - 3 = 10

    x = 13

B) 5x + 8 = 7x

   5x - 7x = -8

   -2x = -8

   x = 4

C) 6x - 5 = 7x

    6x - 7x = 5

    -x = 5

    x = -5

D) 4x + 12 = -6x - 38

    4x + 6x = -12 - 38

    10x = -50

    x = -5

E) 5 . (-x + 3) - 2 = -4x + 6

   -5x + 15 - 2 = -4x + 6

   -5x + 13 = -4x + 6

   -5x + 4x = -13 + 6

   -x = -7

    x = 7
