Question

200. Решите уравнение:

1) 4x = 24 + xz

2) 8x - 8 = 20 - 6x

3) 9 - 4x =3x-40:

4) 0.6x - 5, 4 = 0, 8x + 5, 8

5) 4.7 - 1 1x = 0 5x - 3.3

6) 5/6 * x + 16 = 4/9 * x + 9

Answer 1

Ответ:

1) x = 24/(4-z)

2) x = 2

3) x = 7

4) x = 56

5) x = 8/11.5

6) x = -18

Пошаговое объяснение:

1) 4x - xz = 24, x = 24/(4-z)

2) 8x - 8 = 20 - 6x, 14x = 28, x = 2

3) 9 - 4x = 3x - 40, 7x = 49, x = 7

4) 0.6x - 5.4 = 0.8x + 5.8, 0.2x = 11.2, x = 56

5) 4.7 - 11x = 0.5x - 3.3, 11.5x = 8, x = 8/11.5

6) (5/6)x + 16 = (4/9)x + 9, (7/18)x = -7, x = -18
