Реши уравнение 254+х=1000 z:6=10•10, 100:b=1. y•80=400 a-823=177 10•c=5•20

Найдем корни.

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.
