Question

Equaçao fracionaria x/y = -1/2 x+1/y+1=-1

Answer 1

Resposta:

Explicação passo-a-passo:

x/y = -1/2

x+1/y+1=-1

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

x/y = -1/2

2yx/2y=-y/2y

x=-y/2y

Substituindo:

-y/y=-1/2

y/2y/y= -1/2

2y.y/2y=-y/2y

4y.y/2y=-y

4y/2y=-y

2y=-y

y=-y/2

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

x+1/y+1=-1

x+1=-1(y+1)/y+1

x=-1-1

x=-2

------

-2+1/y+1=-1

-2+1=-1(y+1)/y+1

-1=-y

y=1
