Question

va rog repede urgent ex 6 si 7 punctele d , e , f​

Answer 1

6.) d.) 7-5x= -13

-5x= -13-7

-5x= -20

x= -20/-5

x= 4

e.) 2-9x= -25

-9x= -25-2

-9x= -27

x= -27/-9

x= 3

f.) 6-4x= -22

-4x= -22-6

-4x= -28

x= -28/-4

x= 7

7.) d.) 24: (-x)-7= -13

24:(-x)= -13+7

24:(-x)= -6

-x= 24/-6

-x= -4, x= 4

e.) 32:(-x)-6= -10

32:(-x)= -10+6

32:(-x)= -4

-x= 32/-4

-x= -8, x= 8

f.)45:(-x)-8= -13

45:(-x)= -13+8

45:(-x)= -5

-x= 45/-5

-x= -9, x= 9

Answer 2

Răspuns:

Explicație pas cu pas:

7 - 5x = -13

7 + 13 = 5x

20 = 5x

x = 20 : 5 = 4

_______

2 - 9x = -25

2 + 25 = 9x

27 = 9x

x = 27 : 9 = 3

_________

6 - 4x = -22

6 + 22 = 4x

28 = 4x

x = 28 : 4 = 7

___________________

24 : (-x) - 7 = -13

24 : (-x) = 7 - 13 = -6

x = 24 : 6 = 4

__________

32 : (-x) -6 = -10

32 : (-x) = 6 - 10 = - 4

x = 32 : 4 = 8

__________

45 : (-x) - 8 = -13

45 : (-x) = 8 -13 = -5

x = 45: 5 = 9
