Question

4(x+1)=-16
16/(2x+2)=-4

Answer 1

Răspuns:

4(x + 1) = - 16

x + 1 = - 16 : 4

x + 1 = - 4

x = - 4 - 1 = - 5

16/(2x + 2) = - 4

16 = - 4(2x + 2) | : 4

4 = 2x + 2

2x + 2 = 4

2x = - 4 - 2

2x = - 6

x = - 6 : 2 = - 3

Answer 2

SALUT!

4(x+1)=-16

x+1=-4

x=-4-1

x=-5

16/(2x+2)=-4

16/2x+2=-4 , x=-1

16/2(x+1)=-4

8/x1=-4

8=-4(x+1)

2=-(x+1)

x=-1-2

x=-3,x=-1

x=-3
