Найдем корешки.

1) 254 + х = 1 000; 

x = 1 000 - 254;

x = 746.

2) z/6 = 10 * 10; 

z/6 = 100;

z = 6 * 100;

z = 600.

3) 100/b = 1; 

1 * b = 100;

b = 100.

4) y * 80 = 400; 

y = 400/80;

y = 40/8;

y = 5.

5) a - 823 = 177; 

a = 177 + 823;

a = 180 + 820;

a = 200 + 800;

a = 1 000.

6) 10 * c = 5 * 20; 

10 * c = 100; 

c = 100/10; 

c = 10.
