Question

решите номер 2 срочно!!

Answer 1

a) х+6 19/26=8 1/39
    x+175/26=313/39
    x=313/39-175/26=589/78=7 546/78

б) (x+5/12)-1 1/6=1,25
     x+5/12-7/6=1,25
     x=125/100-5/12+7/6=2400/1200=2

Answer 2

1) x=313/39 - 175/26 = (8138-6825)/1014= 1313/1014=1 299/1014

2) x+5/12 = 5/4 +7/6 = (15+14)/12 =29/12
x= 5/12 - 29/12= 24/12 = 2
