y/(1-y)=3

\frac{y}{1 - y} = 3

y = \frac{3}{4}

Decimal Notation

y = 0.75

Solution steps

\frac{y}{1 - y} = 3

Multiply both sides by

1 - y

y = 3 (1 - y)

Expand

3 (1 - y) : 3 - 3 y

y = 3 - 3 y

Move

3 y

to the left side

4 y = 3

Divide both sides by

4

y = \frac{3}{4}

Verify Solutions

Find undefined (singularity) points:

y = 1

Combine undefined points with solutions:

y = \frac{3}{4}

\frac{3}{a} + 4 = \frac{3}{2 a}

\frac{2 x - 1}{x + 3} = - 2

1 - x - \frac{36}{108 x + 18} = 0

\frac{x}{x - 1} = \frac{x + 2}{x}

\frac{3}{x - 1} = \frac{2}{x - 2}
