Решите уравнения:

х*9+36=11*18

304: (х: 6-5) = 16

1) х*9+36=11*18

9x = 11*18-36

9x = 162

x = 18

2) 304 / (х/6 - 5) = 16

преобразуем скобку

х/6 - 5

5x-30 / 30

5 (x-6) / 30

x-6 / 30

304 / (x-6 / 30) = 16

304 * (6 / x-6) = 16

1824 / x-6 = 16

1824 = 16 * (x-6)

16x - 96 = 1824

16x = 1920

x = 120
