Question

ВАРИАНТ 2 1. 7x+10= 5x + 2 2 8x+ 11 = 6x+13 3. 17-2х=5-6x 4. 5-6x=-10х-3 5. 9x+13=7x+5 6. 4-3x=-7x-4​

Answer 1

Пошаговое объяснение:

7х + 10 = 5х + 2

7х - 5х = 2 - 10

2х = -8

х = -8 : 2

х = -4

8х + 11 = 6х + 13

8х - 6х = 13 - 11

2х = 2

х = 2 : 2

х = 1

17 - 2х = 5 - 6х

-2х + 6х = 5 - 17

4х = -12

х = -12 : 4

х = -3

5 - 6х = -10х - 3

-6х + 10х = -3 - 5

4х = -8

х = -8 : 4

х = -2

9х + 13 = 7х + 5

9х - 7х = 5 - 13

2х = -8

х = -8 : 2

х = -4

4 - 3х = -7х - 4

-3х + 7х = -4 + 4

4х = 0

х = 0 : 4

х = 0
