Решите уравнение:
а) $1 - \frac{x}{6} + \frac{x}{10} = 0$;
б) $4 - \frac{2x}{3} + \frac{x}{6} = 0$;
в) $\frac{x}{6} - 2 = \frac{x}{4} + 1$;
г) $\frac{x}{4} + 2 = \frac{x}{10} - 1$.
$1 - \frac{x}{6} + \frac{x}{10} = 0$ |* 30
30 − 5x + 3x = 0
−2x = −30
x = 30 : 2
x = 15
$4 - \frac{2x}{3} + \frac{x}{6} = 0$ |* 6
24 − 4x + x = 0
−3x = −24
x = 24 : 3
x = 8
$\frac{x}{6} - 2 = \frac{x}{4} + 1$ |* 12
2x − 24 = 3x + 12
2x − 3x = 12 + 24
−x = 36
x = −36
$\frac{x}{4} + 2 = \frac{x}{10} - 1$ |* 20
5x + 40 = 2x − 20
5x − 2x = −20 − 40
3x = −60
x = −60 : 3
x = −20
