Question

(X +5/12)-9/20=11/15

Answer 1

Ответ:

(x+5/12)-9/20=11/15

x+5/12-9/20=11/15

x=11/15-5/12+9/20

x=44-25+27

60

x=46/60=23/30

Answer 2

Ответ:

$(x + \frac{5}{12} ) - \frac{9}{20} = \frac{11}{15} \\ x + \frac{5}{12} - \frac{9}{20} = \frac{11}{15} \\ x + \frac{25 - 27}{60} = \frac{11}{15} \\ x - \frac{1}{30} = \frac{11}{15} \\ x = \frac{11}{15} + \frac{1}{30} = \frac{22 + 1}{30} = \frac{23}{30}$
