Question

{х+7/3 - у-8/5=3

{х+5/4 + у+9/3=5

Answer 1

{x+11/15-y = 3

+

{x+5/12+y = 5

_____________

2x + 897/150 = 8

2x = 8-4 целых177/180

2x = 7 целых 180/180 - 4 целых 177/180

2x = 3 целых 3/180

x = 543/180/2/1

x = 543/2*180 = 543/360

 

543/360 + 51/12 + y = 5

y = 5-543/360 - 51/12

y = 5-987/360

y = 4 целых 360/360 - 987/360

y = 2 целых 113/360

 

Ответ ( 543/360 ; 113/360)
