e)-16:x=-4
f)-18:x=-2
g)-27:x=-3
h)-35:x=-7

Answer 1

Răspuns:

Explicație pas cu pas:

a)

20 : x = - 5

x = 20 : (- 5) = - 4

b)

28 : x = - 7

x = 28 : (- 7) = - 4

c)

36 : x = - 6

x = 36 : (- 6) = - 6

d)

42 : x = - 6

x = 42 : (- 6) = - 7

e)

- 16 : x = - 4

x = - 16 : (- 4) = 16 : 4 = 4

f)

- 18 : x = - 2

x = - 18 : (- 2) = 18 : 2 = 9

g)

- 27 : x = - 3

x = - 27 : (- 3) = 27 : 3 = 9

h)

- 35 : x = - 7

x = - 35 : (- 7) = 35 : 7 = 5
