Question

По математике надо решить уравнения с дробями X- 5|12= 2|12

X+ 7|19= 11|19

7|25 +X= 18|25

X+ 12|25= 16|25​

Answer 1

1) х = 7/12

2) х= 4/19

3) х = 11/25

4) х = 4/25

Answer 2

1)

$x - \frac{5}{12} = \frac{2}{12} \\ x = \frac{2}{12} + \frac{5}{12} \\ x = \frac{7}{12}$

2)

$x + \frac{7}{19} = \frac{11}{19} \\ x = \frac{11}{19} - \frac{7}{19} \\ x = \frac{4}{19}$

3)

$\frac{7}{25} + x = \frac{18}{25} \\ x = \frac{18}{25} - \frac{7}{25} \\ x = \frac{11}{25}$

4)

$x + \frac{12}{25} = \frac{16}{25} \\ x = \frac{16}{25} - \frac{12}{25} \\ x = \frac{4}{25}$
