Answer 1

1)

$11x = 36 - x \\ 11x + x = 36 \\ 12x = 36 \\ x = 36 \div 12 \\ x = 3$

2)

$9x + 4 = 48 - 2x \\ 9x + 2x = 48 - 4 \\ 11x = 44 \\ x = 44 \div 11 \\ x = 4$

3)

$8 - 4x = 2x - 16 \\ - 4x - 2x = - 16 - 8 \\ - 6x = - 24 \\ 6x = 24 \\ x = 24 \div 6 \\ x = 4$

4)

$4(x - 6) = x - 9 \\ 4x - 24 = x - 9 \\ 4x - x = - 9 + 24 \\ 3x = 15 \\ x = 15 \div 3 \\ x = 5$

5)

$6 - 3(x + 1) = 7 - 2x \\ 6 -3 x - 3 = 7 - 2x \\ - 3x + 2x = 7 - 3 \\ - x = 4 \\ x = - 4$

6)

$(8x +3 ) - (10x + 6) = 9 \\ 8x + 3 - 10x - 6 = 9 \\ - 2x = 9 + 3 \\ - 2x = 12 \\ x = 12 \div ( - 2) \\ x = - 6$

7)

$8(5 - 3x) = 6(2 - 4x) + 7 \\ 40 - 24x = 12 - 24x + 7 \\ - 24x + 24x = 19 - 40 \\ 0 = - 21$

Answer 2

Пошаговое объяснение:

11х = 36 - х

11х + х = 36

12х = 36

х = 36 : 12

х = 3

9х + 4 = 48 - 2х

9х + 2х = 48 - 4

11х = 44

х = 44 : 11

х = 4

8 - 4х = 2х - 16

-4х - 2х = -16 - 8

-6х = -24

х = -24 : (-6)

х = 4

4(х - 6) = х - 9

4х - 24 = х - 9

4х - х = -9 + 24

3х = 15

х = 15 : 3

х = 5

6 - 3(х + 1) = 7 - 2х

6 - 3х - 3 = 7 - 2х

3 - 3х = 7 - 2х

-3х + 2х = 7 - 3

-х = 4

х = -4

(8х + 3) - (10х + 6) = 9

8х + 3 - 10х - 6 = 9

-2х - 3 = 9

-2х = 9 + 3

-2х = 12

х = 12 : (-2)

х = -6

8(5 - 3х) = 6(2 - 4х) + 7

40 - 24х = 12 - 24х + 7

40 - 24х = 19 - 24х

40 = 19

Утверждение ложно для любого значения х

х Є ∅
