7-176.

Solve each of the following equations. Be sure to check your solutions.

1. $\frac { 3 } { x } + \frac { 2 } { x + 1 } = 5$

Find a common denominator.

1. $x^{2} + 6x + 9 = 2x^{2} + 3x + 5$

Set the equation equal to zero and factor.

1. $8 - \sqrt { 9 - 2 x } = x + 3$

Subtract 8 from both sides and then square both sides.
