Question

Решите уравнение а)(x+5/12)-9/20=11/15
б) (x+4/25)-21/50=34/75

Answer 1

A)(x+5/12)-9/20=11/15
x+5/12-9/20=11/15
x=11/15-5/12+9/20
x=23/30
ответ:23/30

б)(х+4/25)-21/50=34/75
х+4/25-21/50=34/75
х=34/75-4/25+21/50
х=107/150
ответ:107/150....:)

Answer 2

(x+5/12)-9/20=11/15
x+5/12 - 9/20 = 11/15
x=11/15-5/12+9/20
11/15 - 5/12 + 9/20 = (11*4)/60 - (5*5)/60 + (9*3)/60 = (44-25+27)/60 = 46/60=23/30
x=23/30

(x+4/25)-21/50=34/75
x+4/25 - 21/50 = 34/75
x=34/75-4/25+21/50
34/75-4/25+21/50 = (34*2-4*6 + 21*3)/150 = 107/150
x=107/150
