Answer 1

1)x+4,83=9
x=9-4,83
x=4,17

2)43,78-x=5,384
-x=5,384-43,78
-x=-38,396
x=38,396

3)x-14,852=15,148
x=15,148+14,852
x=30

4)2,395+x=10
x=10-2,395
x=7,605

Answer 2

№ 868
х + 4,83 = 9
х = 9 - 4,83
х = 4,17
-------------------
43,78 - х = 5,384
х = 43,78 - 5,384
х = 38,396
------------------
х - 14,852 = 15,148
х = 15,148 + 14,852
х = 30
------------------
2,385 + х = 10
х = 10 - 2,385
х = 7,615
