Answer 1

540 :x = 380 :19
540:x=20
X=540:20
X=27

Answer 2

1. 540 : x = 380 : 19
540 : x = 20
х = 540 : 20
х = 27

2.x * 6 = 18 000 + 24
6х = 18024
х = 18 024 : 6
х = 3 004

3. 3 480 - х = 2 190 : 3
3 480 - х = 730
х = 730 + 3 480
х = 4 210

4. х + 2 010 = 3 001 * 4
х + 2 010 = 12 004
х = 12 004 - 2 010
х = 9 994
