(y-1)/(y+1)= 3/(y+3)

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

y = 3, y = - 2

Solution steps

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

Cross multiply

(y - 1) (y + 3) = (y + 1) \cdot 3

Solve

(y - 1) (y + 3) = (y + 1) \cdot 3 : y = 3, y = - 2

y = 3, y = - 2

Verify Solutions

Find undefined (singularity) points:

y = - 1, y = - 3

Combine undefined points with solutions:

y = 3, y = - 2

\frac{2}{3 x + 1} = \frac{5}{8 x + 1}

\frac{27}{x} = \frac{x}{3}

y, x = \frac{2 y + 1}{y + 3}

\frac{1}{x + 1} + 3 = \frac{7}{x + 1}

2 x + \frac{12}{x} = 11

What is the answer to (y-1)/(y+1)= 3/(y+3) ?
The answer to (y-1)/(y+1)= 3/(y+3) is y=3,y=-2
Solve for y: (y-1)/(y+1)= 3/(y+3)
The solution is y=3,y=-2
