Question

Hallar x

-42x+5= -16

5/9x+1(11 sobre 9 x-4)=28

10-3x+5 sobre 6 =3 11 sobre 2-x sobre 2/4

Answer 1

-42x=-16-5
x= -21:(-42)
x= 7/14

5/9x+1.(11/9x-4)=28
5/9+11/9x-4=28
11/9x=28-5/9+4
x= 283/9:11/9
x= 2547/99

Answer 2

Respuesta:

Explicación paso a paso:

- 42x + 5 = - 16

- 42x = - 16 - 5

- 42x = - 21

42x = 21

x = 21/42

x = 1/2

----------------------------------------------------------

5/9x + 1 (11/9x - 4) = 28

5x/9 + (11x/9 - 4) = 28

9 (5x/9) + 9 (11x/9 - 4) = 9 (28)

5x + 9 (11x/9 - 4) = 252

5x + 99x/9 - 36 = 252

5x + 11x = 288

16x = 288

x = 288/16

x = 18
