1.  2n + 5 = 27; n = 11

2.  7(4 + n) = -14; n = -6
3.  4n + 3 = 2n – 9; n = -6

                                            25 + 5h         =            30.76 + 3h
                                            25 + 2h         =             30.76
                                                    2h         =               5.76
                                                      h         =               2.88;  $2.88
17.  Since all 3 sides are equal length,
        2x + 5 = 4x – 3
                5 = 2x – 3
                8 = 2x
                4 = x
Now that you know the value of x, substitute 4 for x to find
the length of each side of the triangle.  Each side is
2(4) + 5 = 13 units.  Therefore, the perimeter is
3(13) = 39 units.
