Answer 1

Ответ:

1) 15x - 6x = -8 - 10

9x = -18

x = -2

2) 10x - 4x = -7 + 11

6x = 4

x = $\frac{2}{3}$

3) 11x - 7x = -25 -15

4x = -40

x = - 10

4) -2x + 8 = 3 + 7x

-2x - 7x = 3 - 8

-9x = -5

x = $\frac{5}{9}$

5) 14x -20x = 9 + 25

-6x = 34

x = $-5\frac{2}{3}$

6) 16x -8x = -44 + 28

8x = -16

x = -2

7) 26x - 8x = -42 + 6

18x = -36

x = - 2

8) -15 + 3x = 35 - 5x

3x + 5x = 35 + 15

8x = 50

x = 6,25

9) 4x - 15 = -63 - 7x

4x + 7x = - 63 + 15

11x = -48

x = $4\frac{4}{11}$

10) 10x - 20x = 7 + 8

-10x = 15

x = -1,5

11) 14x - 8x = -43 - 3

6x = -46

x = $7\frac{2}{3}$

12) 17x - 20x = 9 + 8

-3x = 17

x = $-5\frac{2}{3}$

13) 13x - 27x = 18 - 8

-14x = 10

x = $\frac{5}{7}$

14) 18x - 32x = 14 - 9

-14x = 5

x = $-\frac{5}{14}$

15) 21x - 34x = 3 - 24

-13x = -21

x = $1\frac{8}{13}$
