2.решить уравнение: A)98x - 87x = 616; Б) 32x+11x-27x+4=100; B)(16x - 10x + 3). 6 = 198.

Решим уравнения:

А) $$98x - 87x = 616$$

1. $$11x = 616$$
2. $$x = \frac{616}{11}$$
3. $$x = 56$$

Б) $$32x + 11x - 27x + 4 = 100$$

1. $$16x + 4 = 100$$
2. $$16x = 100 - 4$$
3. $$16x = 96$$
4. $$x = \frac{96}{16}$$
5. $$x = 6$$

В) $$(16x - 10x + 3) \cdot 6 = 198$$

1. $$(6x + 3) \cdot 6 = 198$$
2. $$6x + 3 = \frac{198}{6}$$
3. $$6x + 3 = 33$$
4. $$6x = 33 - 3$$
5. $$6x = 30$$
6. $$x = \frac{30}{6}$$
7. $$x = 5$$

Ответ: А) 56; Б) 6; В) 5
