1,18-(0,03х-0,6)*0,2=1,12

1,18 - (0,03 * х - 0,6) * 0,2 = 1,12;

Упростим уравнение.

-0,2 * (0,03 * x 0.6) = 1.12 1.18;

-0.2 * (0.03 * x 0.6) = -0.06;

0.03 * x 0.6 = -0.06/(-0.2);

0.03 * x 0.6 = 0.06/0.2;

0.03 * x 0.6 = 0.6/2;

0.03 * x 0.6 = 0.3;

Приведем уравнение к виду a * x = b.

0.03 * x = 0.3 + 0.6;

0.03 * x = 0.9;

x = 0.9/0.03;

x = 9/0.3;

x = 90/3;

x = 30.
