Question

5x+4 = 1 + 2
------- -- --
X 4 2

Answer 1

Resposta:

5x+4 =  1    +     2

-------     --          --

   x       4          2

Se for (5x+4)/x =1/4+2/2

(5x+4)/x =1/4+4/4

(5x+4)/x=5/4

4*(5x+4)=5x

20x-3x=-16

15x=-16

x=-16/15

Answer 2

Resposta:

x = - 16/15

Explicação passo-a-passo:

5x + 4/x = 1/4 + 2/2

5x + 4/x = 1/4 + 1

5x + 4/x = 1 + 4/4

5x + 4/x = 5/4

4(5x + 4) = 5.x

20x + 16 = 5x

20x - 5x = - 16

15x = - 16

x = -16/15
