РЕШИТЕ С ОБЪЯСНЕНИЕМ (ЕСЛИ НЕ БУДЕТ РЕШЕНИЯ И ОБЪЯСНЕНИЯ ТО ПОЖАЛУЮСЬ)
​

Answer 1

1)

$4\left(x - \dfrac{1}{2}\right) = 0\ \ \ \ \ \Big| :4\\\\\\x - \dfrac{1}{2} = 0\\\\\\\boxed{\bf{x = \dfrac{1}{2}}}$

2)

$8\left(x - \dfrac{3}{14}\right) = 0\ \ \ \ \ \Big| :8\\\\\\x - \dfrac{3}{14} = 0\\\\\\\boxed{\bf{x = \dfrac{3}{14}}}$

3)

$\left(x - 1\dfrac{3}{4}\right)\cdot \dfrac{2}{3} = 0\ \ \ \ \ \Big|: \dfrac{2}{3}\\\\\\x - 1\dfrac{3}{4} = 0\\\\\\\boxed{\bf{x = 1\dfrac{3}{4}}}$

4)

$\left(x - 2\dfrac{1}{4}\right)\cdot \dfrac{4}{5} = 0\ \ \ \ \ \Big| :\dfrac{4}{5}\\\\\\x -2\dfrac{1}{4} = 0\\\\\\\boxed{\bf{x = 2\dfrac{1}{4}}}$
