Question

x/6 + x/4 = x/3 - 1
s = {-12}

Answer 1

$\frac{x}{6} + \frac{x}{4} = \frac{x}{3} - 1$

m.m.c entre 6 e 4:

6, 4|2

3,2|2

3,1|3 12

1,1

$\frac{2x + 3x}{12} = \frac{x - 3}{3}$

$\frac{5x}{12} = \frac{x - 3}{3}$

$5x \times 3 = 12(x - 1)$

$15x = 12x - 12$

$15x - 12x = - 12$

$3x = - 12$

$x = \frac{ - 12}{3}$

$x = - 4$
