Question

102*80-х=456*14 651*20-х=1980-103 х-5004=3021*30 7005*7-х=102*2

Answer 1

1) 8160-x=6384
-x=6384-8160
-x= -1776
x= 1776

2) 13020-x=1877
-x= 1887-13020
-x= -11143
x= 11143

Answer 2

Let's solve the equations step by step:

1. 102 * 80 - x = 456 * 14 8160 - x = 6384 x = 8160 - 6384 x = 1776

2. 651 * 20 - x = 1980 - 103 13020 - x = 1877 x = 13020 - 1877 x = 11143

3. x - 5004 = 3021 * 30 x - 5004 = 90630 x = 90630 + 5004 x = 95634

4. 7005 * 7 - x = 102 * 2 49035 - x = 204 x = 49035 - 204 x = 48831

So, the solutions for the equations are:

1. x = 1776
2. x = 11143
3. x = 95634
4. x = 48831
