решите уравнение:-9 * (6 х+1) - 1.6=5 * (0.1 х-0.5)

-9 * (6 х + 1) - 1.6 = 5 * (0.1 х - 0.5)

-54 х - 9 - 1.6 = 0.5 х - 2.5

-54 х - 10.6 = 0.5 х - 2.5

-54 х - 0.5x - 10.6 = - 2.5

-54 х - 0.5x = 10.6 - 2.5

-х (54 + 0.5) = 8.1

-54.5x = 8.1

-54.5x = 8.1

x = - 8.1 : 54.5

x = - 8 1/10 : 54 5/10

x = - 81/10 : 545/10

x = - 81/10 * 10/545

x = - 81/545 * 10/10

x = - 81/545 * 1

x = - 81/545

Ответ: - 81/545
