4. Examples 6x – 16 = 8 6x – 16 = 8 3 - _x_ = 1 3 - _x_ = 1 9 _54_ = 6 _54_ = 6 x -7x -12 = 16 -7x -12 = 16 _n_ + 9 = 12 _n_ + 9 = 12 3

5. Examples _63_ = 9 _63_ = 9 x 21 = 8x + 5 21 = 8x + 5 34 = 10 + 4c 34 = 10 + 4c Try the first 4 problems on your handouts Try the first 4 problems on your handouts b = 44 b = 44 h = 15 h = 15 r = -13 r = -13 x = 11 x = 11

6. In your groups try problems 1-6 e = 3 e = 3 b = -27 b = -27 q = 55 q = 55 g = 72 g = 72 v = 126 v = 126 x = -7 x = -7
