Question

Реши уравнение ( х + 2/19 ) + 5 целых 11/38 = 7 целых 41/76

Answer 1

x + 2/19=7 41/76 - 5 11/38
x+ 2/19= 7 41/76 - 5 (11*2)/(38*2)
x+ 2/19= 7 41/76 - 5 22/76
x + 2/19= 7-5   (41-22)/76
x + 2/19= 2 19/76
x = 2 19/76 - 2/19
x= 2 19/76  - (2*4)/(19*4)
x= 2 19/76 - 8/76
x= 2 (19-8)/76
x= 2 целых 11/76
