Question

Решите уравнения
5617-x*60=4177,x*700-460=289000,y*700=289999+461,d*700=288999+459

Answer 1

5617 - х * 60 = 4177
60х = 5617 - 4177
60х = 1440
х = 1440 : 60
х = 24

х * 700 - 460 = 289000
700х = 289000 + 460
700х = 289460
х = 289460 : 700 = 289460/700 = 14473/35 = 413 18/35


у * 700 = 289999 + 461
у * 700 = 290460
у = 290460 : 700 = 290460/700 = 14523/35 = 414 33/35

d * 700 = 288999 + 459
d *700 = 289458
d = 289458 : 700 = 289458/700 = 413 179/350
