Question

Сколько будет 6s=420000 . 3a=45 . 0+t=80 . 7t=70/2 . 2y=10 . 240000/a=72/9 . 8x=152000/5 . 9b=810/9 . 6a=300 . 4c=20 . 8c=1600 . 7x=35 . 5x=600-100

Answer 1

S=420000/6 => s=70000, a=45/3 => a=15, t=80-0 => t=80,  t=(70/2)/7 => t=5,  y=10/5 => y=2, a=(240000*9)/72 => a=30000, x=152000/(8*5) => x=3800, b=810/(9*9) => b=10
всё... надеюсь понятно)))

Answer 2

6s=420000
s=420000:6
s=70000

3a=45
a=45:3
a=15

0+t=80
t=80-0
t=80

7t=70/2
7t=35
t=35:7
t=5

2y=10
y=10:2
y=5

240000/a=72/9
240000:a=8
a=240000:8
a=30000

8x=152000/5
8x=30400
x=30400:8
x=3800

9b=810:9
9b=90
b=90:9
b=10

6a=300
a=300:6
a=50

4c=20
c=20:4
c=5

8c=1600
c=1600:8
c=200

7x=35
x=35:7
x=5

5x=600-100
5x=500
x=500:5
x=100
