Which of the following equations could you solve by first adding six and then dividing by negative three? 3x - 6 = -9 6 - 3x = -9 -3x - 6 = -9 + 6 = -9

Answer: [tex]-3x-6=-9[/tex]Step-by-step explanation: The proccedure shown in the problem is applied to solve for x and calculate its value. One of the equations shown in the problem is: [tex]-3x-6=-9[/tex] To solve for x you must_ - Add 6 to both sides of the equations: [tex]-3x-6+6=-9+6[/tex] [tex]-3x=-3[/tex] - Then you must divide by -3: [tex]\frac{-3x}{-3}=\frac{-3}{-3} \\x=1[/tex] Then the answer is: [tex]-3x-6=-9[/tex]
