-3x + 32 - 7x = -2(5x + 10)          Given
-3x + 32 - 7x = -10x - 20              Apply the distributive to the parentheses
-10x + 32 = -10x - 20                   Combine like terms
32 = - 20                                      Add 10x to both sides

32 does not -20; this equation has no solutions.
