Answer: -5
Step-by-step explanation: First multiply (x+3) by 3. You should get 3x + 9 = -6. Then you are supposed to isolate the X and to do this we first get rid of the 9. To do this we subtract nine on both sides and you should get 3x = -6 - 9. You can add the negative 9 and the negative 6 to get negative 15 ( 3x = -15). Now you need to isolate the x in (3x) and to do this we need to divide by three on both sides. When you divide three on both sides (3x) becomes X and (-15) becomes -5. SO [X = -5]
