Question

Найдите корень уравнения

---

Answer 1

1) -4x + 4 = -6

-4x = -6 - 4

-4x = -10

x = 2.5

2) -5x - 1 = 4

-5x = 4 + 1

-5x = 5

x = -1

3) -4x + 8 = -7

-4x = -7 - 8

-4x = -15

x = 3.75

4) 10x + 1 = 6x

10x - 6x = -1

4x = -1

x = - 0.25

5) 9x + 6 = 10x

9x - 10x = -6

-x = -6

x = 6
