Question

как решить уравнение - 2000:f-670=1330 и 1600:80+t=60

Answer 1

2000/f-670=1330
2000/f=1330+670
f=2000|2000
f=1

1600|80+t=60
t=60-1600|80
t=60-20
t=40

Answer 2

2000:f-670=1330
2000:f=1330+670
2000:f=2000
f=2000:2000
f=1
2000:1-670=2000-670=1330
1330=1330

1600:80+t=60
t=60-1600:80
t=60-20
t=40
1600:80+40=20+40=60
60=60
