How do I solve this?

Question

The problem is y=x/1-x and to solve for x. I'm not stupid or anything (Doin college algebra and I'm in 6th grade) but I never seen this problem! How do I solve this?

Answer 1

I'm assuming you mean y=x/(1-x) because if not:

y=x/1-x
y=x-x
y=0
x would equal all real numbers

for y=x/(1-x) multiply both sides by the denominator of the right side
x=y(1-x)

Answer 2

The reciprocal of x/(1-x) = (1-x)/x to the negative 1 power
In other words, (1/x - 1)^-1
Therefore 1/y = (1/x - 1)
1/y + 1 = 1/x
(1+y)/y = 1/x
y/(1+y) = x

Answer 3

x=y/(1+y)

Solution:
Multiply bs by (1-x)
(1-x)y = x

Expand
y-xy = x

Carry over
y = x + xy

Factorise
y = x(1 + y)

Divide by (1+y)
y/(1+y) = x

Answer 4

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

Answer 5

if you mean y=(x/1) -x,
y=x-x
y=0

if you mean y=x/(1-x),
y=(x/1) - (x/x)
y=x - 1

Answer 6

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

Answer 7

no idea;y =0; but x?incomputable.u need another eqn.and sole simultaneously.Ask ur teacher.Or is there a misprint?
