Answer 1

Răspuns:

Explicație pas cu pas:

a = (b + c + d) : 3

b = (a + c + d) : 3

c = (a + b + d) : 3

d = (a + b + c) : 3

(a + b + c + d) : 4 = 1,23

a + b + c + d = 1.23*4 = 4,92

b + c + d = 3a

a + c + d = 3b

a + b + d = 3c

a + b + c = 3d

___________

b + c + d = 3a

a + b + c + d = 3a + a

4,92 = 4a ⇒ a = 4,92 : 4 = 1,23

a + c + d = 3b

b + a + c + d = 3b + b

4,92 = 4b ⇒ b = 4,92 : 4 = 1,23

a + b + d = 3c

c + a + b + d = 3c + c

4,92 = 4c ⇒ c = 4,92 : 4 = 1,23

a + b + c = 3d

d + a + b + c = 3d + d

4,92 = 4d ⇒ d = 4,92 : 4 = 1,23
