Question

решите уравнение :x+1/36=1/4+19/36

Answer 1

$x + \frac{1}{36} = \frac{1}{4} + \frac{19}{36} \\ \\ \frac{1}{4 } + \frac{19}{36} = \frac{9 + 19}{36} = \frac{28}{36} = \frac{7}{9} \\ \\ x + \frac{1}{36} = \frac{7}{9} \\ \\ x = \frac{7}{9} - \frac{1}{36} = \frac{28 - 1}{36} = \frac{27}{36} = \frac{3}{4} \\ \\ x = \frac{3}{4}$
