Question

Resuelva esta ecuación: x+2-3x+8=4x+9(2-1)

Answer 1

La ecuación que tienes es:

x + 2 - 3x + 8 = 4x + 9 (2 - 1)
x - 3x + 2 + 8 = 4x + 9 (1)
x - 3x + 2 + 8 = 4x + 9
- 2x + 10 = 4x + 9
- 2x - 4x = 9 - 10
- 6x = - 1
x = - 1/-6
x = 1/6

Respuesta.
x = 1/6

COMPROBAMOS LA SOLUCIÓN
x+2-3x+8=4x+9(2-1)
1/6 + 2 - 3 (1/6) + 8 = 4 (1/6) + 9 (2 - 1)
1/6 + 2 - 3/6 + 8 = 4/6 + 9 (1)
1/6 - 3/6 + 2 + 8 = 4/6 + 9
(1 - 3)/6 + 10 = 4/6 + 9
- 2/6 + 10 = (6 * 9 + 4)/6
(6 * 10 - 2)/6 = (54 + 4)/6
(60 - 2)/6 = 58/6
58/6 = 29/3
29/3 = 29/3

La solución es correcta!
