Реши уровнение x/20=40x3 Yx110=110 x-260=0 210/x=420/6 480/x=480 y+0=300

Найдем корни уравнений.

1) x/20 = 40 * 3; 

x/20 = 120;

Умножим крест на крест.

x = 20 * 120;

x = 3600.

2) Y * 110 = 110; 

y = 110/110;

y = 1.

3) x - 260 = 0; 

x = 0 + 260;

x = 260.

4) 210/x = 420/6; 

210/x = 70;

21/x = 7;

7 * x = 21;

x = 21/7;

x = 3.

5) 480/x = 480; 

480 * x = 480;

x = 480/480;

x = 1.

6) y + 0 = 300; 

y = 300.
