(X+4)*6-2+X:2+7-X=18

Answer 1

La ecuación que tienes es:
(x + 4) * 6 - 2 + x/2 + 7 - x = 18
6 (x + 4) - 2 + x/2 + 7 - x = 18
6x + 24 - 2 + x/2 + 7 - x = 18
6x + x/2 + 24 + 7 - 2 - x = 18
6x + x/2 + 31 - 2 - x = 18
6x - x + x/2 + 29 = 18
5x + x/2 = 18 - 29
(5x * 2 + x)/2 = - 11
(10x + x)/2 = - 11
11x/2 = - 11
11x = 2 (- 11)
11x = - 22
x = - 22/11
x = - 2

Respuesta.
x = - 2
