10-100.

Solve each of the following equations.

$\frac { x } { x + 1 } = \frac { 5 } { 7 }$
Hint (a):
See the help for problem 9-108.

$\frac { 2 } { y } = \frac { 3 } { y + 5 }$

$\frac { x } { x + 1 } + \frac { 2 } { x - 1 } = \frac { 8 } { x ^ { 2 } - 1 }$
Answer (c):
$x = -3, 2$

$\frac { 2 } { y + 5 } - \frac { 3 } { y } = \frac { 3 } { y + 5 }$
Answer (d):
$y=\frac{15}{4}$
