Answer: x=-8

Step-by-step explanation: 12-5x+6x=4                                                                 1. Combine like terms: -5x+6x+12=4                                                                       2. Simplify: x+12-12=4-12                                                                                         3. Subtract 4 from -12 so that you can find out what x is: x=-8
