Решите уравнение 2 (x - 7 0 = 18, 2 (x + 5) = 30, 4 (x - 6) = 64, 6 (x + 3) = 96

Вычислим корни уравнений.

1) 2 * (x - 7) = 18;

x - 7 = 18/2;

x - 7 = 9;

x = 9 + 7;

x = 16.

2) 2 * (x + 5) = 30;

x + 5 = 30/2;

x + 5 = 15;

x = 15 - 5;

x = 10.

3) 4 * (x - 6) = 64;

2 * (x - 6) = 32;

x - 6 = 32/2;

x - 6 = 16;

x = 16 + 6;

x = 22.

4) 6 * (x + 3) = 96;

x + 3 = 96/6;

x + 3 = 60/6 + 36/6;

x + 3 = 10 + 6;

x + 3 = 16;

x = 16 - 3;

x = 13.
