5 - 9x = 8x - 12
12 + 5 = 8x + 9x
17 = 17x
17 / 17 = x
1 = x
________________________
7 + 2 - x = - 9x - 1
9x - x = - 1 - 7 - 2
8x = - 10
x = - 10 / 8
x = - 5 / 4
__________________________
3x + 2x = 10 - 5
5x = 5
x = 5 / 5
x = 1
___________________ - 7x + 2 - 3 = 6x - 1 = 6x + 7x - 1 = 13x - 1 / 13 = x
Un abrazo y dame like.
C ;
A) 5 - 9x = 8x - 12 - 9x - 8x = - 12 - 5 - 17x = - 17 x = - 17 / - 17 x = 1
b)7 + 2 - x = - 9x - 1 - x + 9x = - 1 - 7 - 2 8x = - 10 x = - 10 / 8 x = - 1, 25
c)3x + 2x = 10 - 5 5x = 5 x = 5 / 5 x = 1
d) - 7x + 2 - 3 = 6x - 7x - 6x = - 2 + 3 - 13x = 1 x = 1 / - 13 x = - 0, 07
Espero te sirva : ).
